Refactored RAM disk device instantiation to use a ram_disk_data struct
as the device data, instead of assigning disk_info directly.
This change was made to enable adding additional device-specific data
in the future, improving flexibility for RAM disk devices.

In the SL_WIFI_SCAN_TYPE_ADV_SCAN path, the Kconfigs
ADV_ACTIVE_SCAN_DURATION / ADV_PASSIVE_SCAN_DURATION were used only as
a fallback when the per-call wifi_scan_params dwell fields were 0, so
any non-zero per-call value would override them and reach the radio.
BG-scan dwell is a system-tuned policy controlled by Kconfig (like
trigger_level and enable_multi_probe); per-call dwell fields belong to
the foreground scan path only. Always use the Kconfig values for
advanced_scan_config and ignore per-call params on this path.

A capture cycle (configure -> START -> read -> STOP) without a following
RELEASE leaked memory slab blocks: dmic_stm32_dfsdm_stop() tore down the
HAL but never freed the in-flight buffer the driver still owns, and the
completed buffers sitting in the RX queue were never reclaimed. Each
stop/start cycle therefore leaked at least one block, and with a small
slab the next start's k_mem_slab_alloc() eventually failed with -ENOMEM,
surfaced to the caller as -EIO by the START trigger.
Free the in-flight buffer once conversions and their IRQs are stopped,
purge any completed-but-unread buffers from the RX queue on a fresh
start, and drop both on the deinit path so a stream can be stopped and
restarted indefinitely.

Hard-code RegularParam.Trigger to DFSDM_FILTER_SW_TRIGGER in the static
filter initializer. The previous DT_PROP(flt, filter0_sync) value was a
misuse of that binding property: filter0-sync describes an InjectedParam
synchronisation mode and is only valid on filter instances 1-3. On
filter@0 it expanded to 0 (the same value as DFSDM_FILTER_SW_TRIGGER) only
by coincidence; on a hypothetical filter@1+ with filter0-sync set it would
silently turn regular conversions into a sync-trigger. Use the literal
that matches what the driver actually does (software-triggered regular
conversions) and leave the DT property where it belongs, on InjectedParam.

HAL_DFSDM_ChannelInit() writes (Awd.Oversampling - 1) into the
CHAWSCDR.AWFOSR field and asserts that the ratio is in [1, 32]. The
static channel initializer in DMIC_DFSDM_CHAN_DEFINE() left
.Oversampling = 0, so:
- in debug/asserts-enabled builds the HAL assert fires immediately
from HAL_DFSDM_ChannelInit();
- in release builds CHAWSCDR is programmed with a wrap-around value
instead of a valid analog-watchdog oversampling ratio.
Default the static struct to a complete, valid configuration
(Oversampling = 1, FilterOrder = DFSDM_CHANNEL_FASTSINC_ORDER) so the
HAL contract is honoured before any runtime reconfiguration takes
place.

WiseConnect zeros the BT half of its cached coex performance profile
on every Wi-Fi disconnect, leaving BT out of power save and preventing
the NWP from sleeping after re-association.
Delegate Wi-Fi power-save to siwx91x_nwp_apply_power_profile(), which
already owns both BT and Wi-Fi halves of the coex profile. Extend the
helper to accept an optional sl_wifi_performance_profile_v2_t override
so the Wi-Fi driver can pass its tailored profile (listen_interval,
dtim_aligned_type, monitor_interval); BT-only and init call sites pass
NULL to keep their current behaviour.

crc16_reflect() and crc16_ansi() pass a CRC16 context with the
reflected polynomial 0xA001 and both reflect flags set. The driver
only accepted the normal-form 0x8005 and rejected 0xA001 with -EINVAL,
so those helpers returned 0 and the subsys.crc Ztest suite failed on
NXP parts such as frdm_mcxn947.
The CRC engine takes the polynomial in normal (MSBit-first) form and
reflects via reflectIn/reflectOut, so 0xA001 and 0x8005 describe the
same CRC-16. Accept 0xA001 only when both reflect flags are set and
always program 0x8005; a non-reflected 0xA001 is still rejected.
Tested with tests/subsys/crc on frdm_mcxn947: pass = 14, fail = 0.

Per the SX1261/2 datasheet (13.1.12) 0x000000 selects Rx Single mode
and 0xFFFFFF Rx Continuous mode; the two defines had their values
swapped.
No functional change: SX126X_RX_TIMEOUT_SINGLE (0xFFFFFF) was never
referenced, and the continuous receive paths (lora_recv_async, and
lora_recv with K_FOREVER) re-arm RX after every packet in
sx126x_rx_restart(), so they kept receiving even with the chip wrongly
in single mode. The blocking recv path needs only one packet and
sleeps the radio in the RxDone handler regardless. After the swap
those paths use true Rx Continuous mode, with identical observable
behavior.

GPR bit 0 is Write-Only (WO per DM9051A spec), reading returns
undefined values (default XXh). The previous code read GPR and only
powered on the PHY if bit 0 was set to 1. If the read returned 0x00
(random undefined value), the PHY would never be powered on.
Fix by unconditionally writing GPR = 0x00 to power up the PHY,
ensuring it is always enabled regardless of any prior state.

Now that we have a common data struct, we can take advantage of it and
move the recv callback into it. This way the common layer takes care of
assigning, dispatching and clearing the callback. Drivers now have to use
the new bt_hci_recv() API to pass data to the layer above them (typically
a host stack). Additionally, the drivers no longer get a recv parameter as
part of their open() callback, since that's all handled by the common
layer.

Add a display driver for monochrome and grayscale LED matrices driven by
charlieplexed GPIOs. With N GPIO lines such a matrix can drive up to
N*(N-1) LEDs: each pixel sits between an ordered pair of lines and is lit
by driving one line high and one low while every other line is held at
high impedance. Only one LED is lit at a time; a timer scans the pixels
fast enough for persistence of vision.
The driver implements the display API. It keeps a per-pixel framebuffer
and uses a counter device as the scan time source, lighting the next
pixel on each top-value callback. Grayscale is produced by duty
modulation over a configurable number of sub-frames. To stay portable
across SoCs it drives the matrix purely through the generic GPIO API,
configuring the inactive lines as disconnected to obtain the required
high-impedance state rather than touching the GPIO registers directly.
The GPIO bank, the per-pixel high/low pin-pair map, the scan timer,
refresh rate and grayscale depth are all described in devicetree through
the new charlieplex-led-matrix binding.
