Rename UARTE_ANY_FAST to UARTE_ANY_FAST_PD. There are 2 types of
'fast' UARTE instances. In nrf54h20 instance uart120 is in fast
power domain that requires additional power and clock management
of that domain. In nrf54lx fast uart00 instance does not require
that. Add _PD to indicate fast power domain.

When using asynchronous API, transfer will fail if the source buffer is
located in a region that cannot be accessed by DMA. This could happen
when a buffer is declared const, and placed in flash memory, for
example.
Workaround this problem by loading the data into a set of temporary
caches before passing them to DMA.

This commit adds asynchronous mode support to MAX32 UART driver. Each
direction uses a single DMA channel that is assigned in devicetree

Asynchronous mode also depends on interrupts to refresh receive
timeouts.

In the application, after the sysjump, the RX interrupt might remain
enabled. During initialization, once the IRQ is enabled, the RX
interrupt could be triggered if there is any traffic on the RX line,
potentially causing an interrupt storm.
This change disables the UART RX interrupt at the driver initialization
to prevent this issue from occurring.

The Atmel SAM0 SoC enable peripherals clocks in distinct places: PM and
MCLK. The old devices had defined the peripheral clock enable bit at PM.
On the newer devices this was extracted on a dedicated memory section
called Master Clock (MCLK). This change excludes the dedicated bindings
in favor of a generic approach that cover all cases.
Now the clocks properties is complemented by the atmel,assigned-clocks
property. It gives the liberty to user to customize the clock source
from a generic clock or configure the direct connections.
All peripherals drivers were reworked with the newer solution.

Some time ago a new shim for nRF UARTE was added (uart_nrfx_uarte2.c)
which used nrfx_uarte.c driver underneath. It was supposed to support
nrf54x platforms. However, later on legacy driver (uart_nrfx_uarte.c)
was extended to support nrf54x platforms and it takes less code size,
has better performance and more features. Shim uart_nrfx_uarte2 will
no longer be supported. As new shim is the default and there is a
Kconfig to pick the legacy shim (CONFIG_UART_NRFX_UARTE_LEGACY_SHIM=y)
it cannot be deprecated in the normal way. Additional Kconfig option
is created (DEPRECATED_UART_NRFX_UARTE_LEGACY_SHIM) which is enabled
if CONFIG_UART_NRFX_UARTE_LEGACY_SHIM=n and it selects DEPRECATED.
A warning was also added to the CMakeLists.txt.
Patch removes use CONFIG_UART_NRFX_UARTE_LEGACY_SHIM in tests.

- DMA_STATUS_COMPLETE(0), DMA_STATUS_BLOCK(1) macros to handle half

- add ASYNC_UART_STATUS_TIMEOUT(3) macro to work with default mode
- add status input in uart_stm32_dma_rx_flush function to handle
async events depending on the mode we are in.

Request fast global domain to run at 320 MHz during fast UARTE
activity. As request is asynchronous it cannot be called from
an ISR. Due to complexity to handle that without device runtime
power management a requirement is added so that if fast UARTE
is used device runtime PM must be enabled. Clock is request
and released in PM resume and suspended actions which in case
of fast UARTE are only called from thread context.

Low power mode for non-asynchronous API case is only available when
RX is not used (RX pin is not defined). In that case TX starting
function was using uarte_enable_locked() which tracks if UARTE is
used by TX or RX and TXSTOPPED interrupt was disabling UARTE
unconditionally. Because of that following attempt to TX start
was assuming that UARTE is already enabled when it was disabled.
Fixing it by using uarte_disable_locked function in TXSTOPPED
handling.
Code reordering was required to make uarte_disable_locked()
available earlier.

When fast UARTE instance is used (e.g. UARTE120 in nrf54h20), PM actions
are not ISR safe because they include communication over IPC so they can
only be called from the thread context. Extend driver to support both
PM modes. When non ISR mode is used then uart_rx_enable() and uart_tx()
will return error if they are called from ISR and resume operation
would need to be called because device is suspended. On completion,
driver is calling pm_device_runtime_put_async which can be called from
the ISR context.
Additionally, suspending in the TXSTOPPED and RXTO events has been
moved after user callback. It allows to support the case where
uart_rx_enable() or uart_tx() are called from that callback context.
Since suspending is called after returning from the callback it will
not trigger suspend action because API called in the callback context
will increment the usage counter (when pm_device_runtime_get() is
called).

Deprecate mode which is using TIMER+(D)PPI for reliable byte counting.
Recently a new approach is added (CONFIG_UART_NRFX_UARTE_ENHANCED_RX)
which supports reliable byte counting without additional HW resource.
This mode is planned to be the only supported RX path mode.
Enhanced RX has slightly different behavior. There are no partial RX
packets (events with non-zero offset). There is UART_RX_BUF_RELEASED
after each UART_RX_RDY event.
