Due to the alias of ptr on pixels, one iterates over the same area
one reads from to set values. Therefore, if the strip is not 'RGB' but
GBR, one would overwrite the pixels 'r' value with the 'g' value in the
first loop, leading to a wrong read afterwards.
By writing to a temporary variable, we have a clean, unmodified copy
of the original values.
Additionally, this removes the dependency on 'LED_STRIP_RGB_SCRATCH',
as the scratch part (that masked most error cases) is not necessary
anymore.

In several functions, the UART registers are accessed multiple times
through the `get_uart(dev)` inline function. This results in repeated
dereferencing of the device's base address.
This commit caches the UART register struct pointer in a local variable
`uart` at the beginning of each relevant function.
For registers where repeated access is not needed, the value is read once
into a temporary variable. Modifications, if any, are applied to
the temporary copy, and the result is written back once.

Kconfig option UDC_DWC2_USBHS_VBUS_READY_TIMEOUT depends on services
exclusively available for nRF54H20, but the option can also be used for
nRF54LM20A, where there are no service dependencies, and VREG can be
accessed by the driver directly. Let depend the option on the SOC
series, as the controller can be used by the different CPUs on the SOC.

Add support for configuring I3C open-drain speed modes to handle
different timing requirements during bus initialization and operation.
Implementation:
- Fetch current controller configuration
- Invoke configure api inside bus_init to configure
I3C open-drain high period for proper bus
initialization and device compatibility.
The slow speed mode is essential for the first broadcast address
transmission to ensure visibility to all devices on the I3C bus,
particularly those in I2C mode that need to disable their spike
filters when switching to I3C mode. This requirement is specified
in "Table 49 I3C Basic Open Drain Timing Parameters" of the MIPI
ALLIANCE Specification for I3C Basic Version 1.2.

This commit improves the I3C handling of open-drain
timing configurations with the following changes:
- Add OD minimum high_ns and low_ns DT properties
- Implement dw_i3c_init_scl_timing for runtime timing updates
- Initialize scl_od_min configuration from device tree
- Maintain backward compatibility with existing configurations
Requirement (MIPI Specification for I3C Basic v1.2 (16-Dec-2024),
Section 4.3.11.2 & Table 49):
- The MIPI I3C specification mandates different open-drain speeds during
bus initialization as defined in
"I3C Basic Open Drain Timing Parameters".
- The first broadcast address (7'h7E+W) must be transmitted at a slower
open-drain speed to ensure visibility to all devices on the I3C bus,
including legacy I2C devices. This slow speed (minimum 200ns Thigh)
allows I2C devices to properly detect the I3C mode transition and
disable their spike filters before switching to I3C mode. After the
initial broadcast, normal I3C open-drain speeds can be used for
regular operation.

nRF53 series SoCs have a dedicated configurable audio PLL and the ability
to enable MCK bypass via a register value CONFIG.CLKCONFIG. This can
enable higher MCK/LRCK ratios that some I2S peripherals require the host
to generate. Allow an application developer to choose if they want to
initially look for a bypass ratio and, if found, enable bypass in the
NRFX driver. If not, the standard MCK calculation is conducted as normal.

804e502484 fix got reverted as it introduced a bug where callback
with HFCLK started indication was not called because state is not
correctly indicated. BT-dedicated API does not set state and does
not expect to get the callback when HFCLK is started. 804e502484
was intended to fix the bug that was visible on nrf54lx. It was not
visible on nrf52 because of a errata workaround which was calling
HFCLK started callback only when state was set to STARTING and that
was not the case when BT-dedicated API was used. Applying this
`workaround` approach to all cases.
