Microchip XEC has been using the standard NS16550 driver.
Using the standard NS16550 driver requires extra HW programming
for XEC UART in board level and did not support XEC GIRQ interrupt
programming. We add an XEC specific driver and remove UART specific
register programming from the board level and implement interrupt
support. Also, by implementing a SoC specific driver we can add
driver PM in the future.

Make the `lora_recv` operation thread safe by copying memory directly
in the callback instead of deferring copying to the original caller.
To ensure pointer validity, this requires performing operations "inside"
the `modem_release` context.

Ensure that the modem is not asked to perform new operations before the
previous operation completes.
An atomic variable is used instead of a mutex as multiple threads need
to release the lock. A semaphore isn't used as there is no indication
whether `k_sem_give` gives the semaphore or not, which is required to
determine if `Radio.Sleep()` should be run.
`Radio.Sleep()` is only ever run by the context that successfully
releases the modem usage, to guard against double calls.

Transition the receive synchronisation method from a single driver
semaphore to a function specific k_poll_signal. This is required to
allow the modem to be released without introducing race conditions on
the signalling mechanism.
Without this change, the RX can either be signalled before the modem is
released, unblocking the calling thread before the modem is put back to
sleep, or after the modem is released, in which case a second thread
could start using the semaphore before the original thread is signalled.

If no packet was received in the provided timeout, manually transition
to sleep mode. If a packet was received, the rx_done callback
automatically transitions the modem to sleep.

Fixes issue 34879
This PR updates previous PR's 37138 and 37139.

designers. A delay after enabling interrupts is a
more appropriate work-around than depending upon
behavior of ARM DMB instruction.

This is a follow-up to commit 3656ba5ae9.
Do not enforce pull-up resistors to be enabled on RXD and CTS pins
in nRF UART drivers, as in certain hardware designs this may be
undesirable or may even make certain hardware not working.
Instead, provide devicetree properties that allow enabling of those
resistors when it is actually needed.

Fix for issue 34879.
Microchip MEC GPIO hardware can trigger a spurious interrupt when
interrupt detection is set to edge mode especially falling edge mode.
Clearing the status immediately after enabling interrupt detection does
not work because the hardware takes a small number of AHB clocks to
set the status. After interrupt detection enable we use an ARM data
memory barrier to insure the write completes before clearing spurious
status and enabling the interrupt in the GIRQ.

Deprecate the xoroshiro128+ PRNG algorithm in favour of xoshiro128++.
xoshiro128++ is a drop-in replacement which is invisible from the user
perspective.
xoroshiro128+ is unsuitable because it is explicitly a floating-point
PRNG, not a general-purpose PRNG. This means that the lower 4 bits of
the output are actually linear, not random (from the designers,
https://prng.di.unimi.it/). This means 1/8th of the generated data is
not random.
Additionally, xoroshiro128+ is not a 32bit algorithm, it operates on
64bit numbers. For the vast majority of Zephyr devices, this makes the
PRNG slower than it needs to be. The replacement (xoshiro128++) is
32bit, with no loss in state space (still 128 bit).

Instead of passing target states, use actions for device PM control.
Actions represent better the meaning of the callback argument.
Furthermore, they are more future proof as they can be suitable for
other PM actions that have no direct mapping to a state. If we compare
with Linux, we could have a multi-stage suspend/resume. Such scenario
would not have a good mapping when using target states.

According to the documentation the OFF state has to be used when the
devices is fully turned off, ie, power removed. Most drivers were using
a sort of fall-through for all non-active states, leading to behaviors
not following the specifications.

- Remove redundant "noop style" functions.
- Use switch everywhere to handle requested state (not necessary in all

The verb tense for the suspended state was not consistent with other

The difference between low power and suspend states is a thin blur line
that is is not clear and most drivers have used indistinctly. This patch
converges to the usage of the suspend state for low power, since
contrary to the low power state, it is used by both system and runtime
device PM. The low power state is still kept, but its future is unclear
and needs some discussion.

Some devices are using PM_DEVICE_STATE_FORCE_SUSPEND as a sort of low
power state, something that is not correct. In fact, this state is not
an actual state and will be eventually moved, if found necessary, to an
action or command.

The device PM control function will only be called if the requested

Since the state is no longer modified by the device PM callback, just
use the state value.

The callback is now invoked to set the device PM state in all cases, so
the usage of ctrl_command is redundant.

The device PM subsystem already holds the device state, so there is no
need to keep duplicates inside the device. The pm_device_state_get has
been refactored to just return the device state. Note that this is still
not safe, but the same applied to the previous implementation. This
problem will be addressed later.

The USB configuration option is actually a global switch
to enable USB drivers in general, but currently only
the device controller drivers are meant.
USB device controller drivers also have USB_DEVICE_DRIVER option.
Thus the option USB is actually redundant and can be replaced
by the self-explanatory option USB_DEVICE_DRIVER.
The name USB itself is not unique and should not be used as an
configuration option.
With these changes the option USB_DEVICE_DRIVER generally
enables USB device controller drivers. The option USB_DEVICE_STACK
enables USB device support. It is sufficient to enable only option
USB_DEVICE_STACK because it selects USB_DEVICE_DRIVER.
CONFIG_USB Kconfig option is temporary added to subsys/usb/Kconfig.
This is necessary to pass CI and will be removed again
when the USB configuration has been adapted in modules.
