b6d45423c6 Added support for pin retention but it was added
only to the case when device PM is used. There is another mode
in which UARTE is disabled when idle (low power mode) and in
that case pin retention must also be added.

The nrfx_gppi module is an abstraction over nrfx_ppi and nrfx_dppi
drivers. It now has a Kconfig option that is separate from nrfx_dppi and
by default it enables all PPI/DPPI instances, if available.

Passing data by value is more efficient in this context. As such,
revise `poll_out_fn` and `uart_stm32_poll_out_visitor` to accept
the `out` argument by value instead of by address.

The tx fifo empty interrupt is a edge driven interrupt, so if it
is already empty then and the interrupt is enabled, it will not
fire so the isr needs to be triggered manually for the callback.
This also removes the unnecessary interrupt locking in the isr and
removes the receiver timeout interrupt.

RX FIFO flushing on RXTO event should only be performed when
UARTE peripheral might be disable during inactivity and that
happens when low power modes is enabled or when device runtime
PM is used. Flushing was incrementing flush_cnt which was not
used (flushed data is not copied to the next buffer) which
was causing data loss and invalid RX data length reporting.

Generate the Tx service request after the symbol is shifted out of the
UART. This is useful when the UART is connected to an RS485 transducer
which has a separate transmit enable gpio/line. Hence it's important
to know when the transmission actually finishes so that the drive
enable line can be disabled.

Series 0 does not have the TXIDLE status flag. The closest equivalent is
TXC, but it isn't set until the first transmission completes, and is
therefore not safe to use in PM suspend without also separately keeping
track of whether the driver has ever initiated a transmission. For now,
disable the TXIDLE check on devices that don't support it as a minimal
fix for the observed build error. This is effectively equivalent to
reverting the addition of PM support for these devices only. Since these
devices don't have a low-power system timer implementation anyway, the
lack of PM handling does not hurt anything.

Remove mutex locking in favour of the standard IRQ locking mechanism.
The primary problem with the mutex implementation is that mutex locking
is forbidden in ISR's. This means that any logging from an interrupt
context (e.g. LOG_PANIC in an exception handler), will itself trigger
another assertion due its attempt to use a mutex.
Furthermore, mutexes are a relatively heavyweight locking scheme, which
doesn't necessarily make sense in the context of extremely short locking
periods that would be expected from RTT.
This change aligns Zephyr with the default RTT locking scheme, which
uses interrupt masking to perform access control.
Resolves#79403.

Add runtime PM to the driver. When asynchronous or interrupt
driven API is used, there are 3 independent paths for enabling
the device: RX, TX and TX poll_out. TX poll_out requires special
handling because number of poll_out calls does not need to much
number of TXSTOPPED interrupts. To handle that special flag is
added. For standard RX and TX is simpler.

Add basic device power management to USART driver. The initial
implementation only ensures that the TX FIFO is flushed before
allowing the system to go to sleep by polling the TXIDLE status
register.

Typically, a `break` is used in switch-case statements unless an early
