Commit `2844850` inadvertently omitted
`SL_SI91X_CUSTOM_FEAT_SOC_CLK_CONFIG_160MHZ`. This commit restores
the missing flag to ensure proper SOC clock setup.
Additionally, `SL_SI91X_CUSTOM_FEAT_LIMIT_PACKETS_PER_STA` is now enabled
as the default setting, aligning with the driver Kconfig.

Siwx91x support a specific mode slightly better than the old legacy PS
mode.
This mode has to be set on the NWP boot, so it is not easy to configure
it during the runtime. Hence, this patch only provide a compile time
option to enable it.

Silabs siwx91x hardware use specific memory areas to store descriptors
for DMA requests. These areas are tightly coupled between the CPU and
the hardware. This helps in reducing the wait cycles.
Until now these addresses was also hard coded in the DT and in the
linker script. This patch leverage the zephyr,memory-region driver to
centralize the information in the DT.
Then, with this new implementation, the memory mapping is easier to
understand for the reader.

In the case where more than a full tick was unannounced when
sys_clock_set_timeout() was called, the timer driver would
subtract it from the next timeout. However, this is already
done by the caller through the elapsed() function in timeout.c,
leading to the timer interrupt firing too early.
With this fix, SYS_CLOCK_TICKS_PER_SEC can be increased to the
full speed of the low frequency timer. The underlying sleeptimer
API must be called with a timeout of at least 1, and will if needed
increase the value to the minimum value required by the hardware.

silabs_s2 uses simplicity_sdk hal library, which already have by default
a zero latency IRQs mechanism with a hardcoded value. In order to be
aligned with simplicity_sdk, we need to activate Zero Latency IRQ in
Zephyr by default. The level (2) depends on the hardcoded
value in simplicity_sdk (CORE_ATOMIC_BASE_PRIORITY_LEVEL). Without this
fix, if you use an IRQ with a priority of 0 or 1, irq_lock() and
irq_unlock() have no effect for this IRQ.

This driver allow to use Zephyr native IP stack or the IP stack provided
by HAL / WiseConnect.
The WiseConnect implementation may take advantage of the specific
features provided by the 917 (power consumption, speed,
validation...).
Some notable features are not available with this interface:
- It seems Zephyr does not provide API to offload multicast membership
management. User should be to directly call WiseConnect APIs
- Support for ICMP frames is difficult. Note that WiseConnect
automatically answer to ping request. It is just not possible to
send ping requests and receive ping responses.
- Zephyr and WiseConnect both support TLS offloading. However this
patch does not implement it.
- Reentrancy in the WiseConnect side is uncertain.
This implementation has been tested with samples/net/wifi/ (which relies
on subsys/net/lib/shell).

The BT Link Layer needs to get runtime in a timely manner to keep
connections alive and handle other time-critical tasks. This is achieved by
adding a separate thread for it with a meta-IRQ priority, which means it
can preempt other threads. The driver also has an RX thread that passes HCI
messages from the controller to the host stack. This can be a lower
priority cooperative thread, as it doesn't have strict timing requirements.

Silicon Labs Series 2 and newer devices do alternate function
configuration fundamentally differently from Series 0 and 1. Pin routing
is done in a centralized fashion in the GPIO peripheral, as opposed to
having ROUTE registers in every peripheral. The concept of alternate
function location numbers also does not exist, functions are directly
assigned to GPIOs by their port and pin number.
This commit adds a new pinctrl driver for devices that use DBUS. It fully
makes use of pinctrl design principles as outlined in the Zephyr
documentation. The previous driver hard-codes pin properties such as filter
and pull-up/down in the driver itself, while the new driver leaves this up
to the user as configurable DeviceTree properties. The previous driver has
hard-coded support for UART, SPI and I2C, while the new driver has generic
support for all DBUS signals.

DeviceTree, the device uses SYSRTC for timekeeping, and Power Manager

deep sleep. It is not needed on devices that don't have HFXO-SYSRTC
integration, and it is not needed if the application doesn't use deep
sleep.
