Block the SoC from re-entering sleep modes while the RX line is active,
if the RX activity previously woke the device from the sleep states.
This stops the device from continuously transitioning between the two
modes and improves responsiveness.

This include seems redundant as the driver builds fine without
it being included. When including soc.h it also causes issues
if one utilises the xenvm board when compiling. I suggest this
is removed completely as it seems unnecessary to create this
tight coupling to a specific SoC as the driver implementation
is describing itself perfectly well, and works well without
this soc.h-file.

The Xilinx xuartps driver fails to find the correct pre-scaler
parameters for the BAUDDIV and BAUDGEN registers. This fix
corrects that behaviour. The reason why it fails is due to
the stop condition for the search being ill-conditioned.
The stop condition is based on a baudrate error, and this
was chosen to be 3 percent. This would cause the parameter
search to stop too early returning ill-condotioned pre-scaler
parameters. This has been corrected by setting the stop condition
to be 3 permille instead of 3 percent. This change was tested
with an AMD Zynq Ultrascale+ MPSoC ZU3EG.

This driver had some issues with interrupt-driven operation, which
manifested by the console breaking when enabling the Zephyr shell on the
kv260_r5 target for example. Fixed the following:
-Ensure device is fully hardware reset during initialization
-Changed poll_out to be more consistent with other drivers, i.e. only
wait for the UART to accept the character, not for it to be fully
transmitted.
-Added implementation for err_check function, as otherwise there was no
way to detect or clear the error interrupts enabled by irq_err_enable.
-Fixed logic for enabling/disabling interrupts. This should only be done
by explicit enable/disable calls, not as part of fifo_fill etc.
-This hardware does not produce interrupts for TX FIFO empty or RX FIFO
threshold when enabling them if the TX FIFO is already empty or RX FIFO
already contains data. When enabling interrupts in these cases, use a
timer to trigger a user callback to match the normal UART API usage,
similar to the xlnx_uartlite driver.
-Other minor cleanups to interrupt-driven functions.

Rename the driver from uart_native_posix to uart_native_pty.
Including renaming the DTS compatible, and kconfig options, deprecating
the old ones.
And refactor the driver, generalizing it, so we can have any number of
instances.
Note that, unfortunately generalizing to N instances cannot be done
without a degree of backwards compatibility breakage: This driver was
born with all its configuration and selection of the instances based on
kconfig.
When the driver was made to use DT, it was done in a way that required
both DT and kconfig needing to manually coherently enable the 2nd UART.
This has now been fixed, which it means only DT is used to decide how
many instances are avaliable, and UART_NATIVE_POSIX_PORT_1_ENABLE is
just ignored.
Including:
* Deprecate UART_NATIVE_WAIT_PTS_READY_ENABLE: the options is always on
now as it has no practical drawbacks.
* Deprecate UART_NATIVE_POSIX_PORT_1_ENABLE: DTS intanciation defines it
being available now.
* Rename a few functions and in general shorten pseudo-tty/pseudo-
terminal to PTY instead of PTTY.

When using the interrupt UART API, it is expected that the driver will
call the callback function repeatedly while TX interrupt is enabled.
However that is not necessarily the case with the FIFO is enabled.
If the application calls uart_fifo_fill() each time with only one byte
of data, the TX interrupt will never trigger. This is because the 1/8 TX
interrupt trigger threshold is never reached. For this reason, the
callback function should be called multiple times from software as
needed.

Fast instance in nrf54h (uart120) can generate a spurious RXTO event
some time after RXTO event that indicates that RX path is disabled.
The time when event is generated depends on baudrate and when slower
baudrates are used peripheral is disabled on time to not notice it
in the test but with higher baudates issue become visible. In order
to avoid spurious interrupt, RXTO interrupt is disabled during RXTO
event handling and enabled when RX is enabled. This workaround is
applied only for fast instance to avoid unnecessary register
accesses for slower instances.
