MAX32 UART's "almost empty" fires when the FIFO gets down to one byte, but
when sending just one byte, no interrupt is raised, resulting in stalled
TX. Use a timer to ensure the ISR is invoked and TX processing continues in
that scenario.

I manually checked the errata sheets for all STM32Hxx/STM32Uxx parts to
confirm the defect's presence or absence. It appears to have been resolved
in silicon on newer parts (e.g., STM32U3xx family), so hopefully this test
will not need grow further (knock on wood).

Add a UART driver for the VIRTIO console device.
This driver has support for both polling- and interrupt-based i/o,
as well as interacting with up to 32 console ports (disabled by
default). Based on the Xen HVC driver.
Tested with the console subsystem sample programs. Aside from
enabling CONFIG_PCIE, setting CONFIG_HEAP_MEM_POOL_SIZE to a
high enough value (for example 100000) is necessary -- as is done
in the virtiofs sample.

The uart_sam0_irg_rx_ready() function always returns true, even if
interrupt is disabled. This happens because the function do not
evaluate if the interrupt is enable of not. This fixes the issue
by adding the missing check.

Fix a bug where if CONFIG_UART_ASYNC_API was enabled in the config, the

The dma driver was determining src_inc and dst_inc from the
config of the first block buffer and ignoring the config
flags for any additional buffers in the chain, which could
lead to incorrect transfers (e.g. in a multiple rx buffer
case, if the first buffer was to receive to NULL,
but the subsequent buffers were not NULL, the bug
would manifest as all transfers being made with
dst_inc of 0). Change the driver to setup
each dma descriptor according to the addr_adj flag
of each block_buffer.
Add check that peripheral transfers have addr_adj set to
NO_CHANGE instead of assuming it, to help catch errors.
Also now check for invalid addr_adj request of
decrement, which this controller doesn't support.

Transition nrf54h away from the soc specific gpd
(global power domain) driver which mixed power domains, pinctrl
and gpio pin retention into a non scalable solution, forcing soc
specific logic to bleed into nrf drivers.
The new solution uses zephyrs PM_DEVICE based power domains to
properly model the hardware layout of device and pin power domains,
and moves pin retention logic out of drivers into pinctrl and
gpio, which are the components which manage pins (pads).
