If interrupt handler contains while loop which depends on
uart_irq_tx_ready() and uart_fifo_fill is called inside this
loop then if TXSTOPPED event occurs while code executes the
loop then uart_irq_tx_ready() will return true but uart_fifo_fill
will fail to write any bytes. That is because fifo_fill_lock is
cleared in handling of TXSTOPPED. To solve that added clearing
the lock inside uart_irq_tx_ready() if STOPPED event is detected
there.

Added early return from uart_poll_out when uart device is not in
active state. Poll_out is used from many contexts by multiple users
and currently here is no mechanism in power management to disable
them (console, logger when going to inactive power state.
Additionally, moved setting new state when disactivating the device to
ensure that no poll_out will happen after disabling the UARTE.

For drivers that support CONFIG_DEVICE_POWER_MANAGEMENT there are some
cases that look like:
#ifdef CONFIG_DEVICE_POWER_MANAGEMENT
DEVICE_DEFINE()
#else
DEVICE_AND_API_INIT()
#endif
There is no need to special case this as the pm_control_fn argument to
DEVICE_DEFINE will just be ignored in the
!CONFIG_DEVICE_POWER_MANAGEMENT case. So we can cleanup the code a
little and remove the #else cases for the drivers that do this.

There is no need to involve a work queue to control timeouts in
the uart_nrfx_uart driver. Kernel timers are sufficient for those
tasks, and the uart_nrfx_uarte driver may serve as a proof of this.
Replace then those uses of work queue with timers, for consistency
and simplicity, also to avoid potential issues with cancellation of
the delayed work queue items.

Refactoring poll_out to be ready for handling preemption. uart_tx and
uart_fifo_fill modified so they are resilient to being preempted by
uart_poll_out.
Refactored uart_poll_out implementation to be common for interrupt
driven API and asynchronous API. In both APIs active state is detected
by evaluating state of ENDTX and TXSTOPPED events. If anyone is set it
means that new transfer can be started.
Patch is fixing existing issues:
- potential bytes dropping with flow control enabled
- busywaiting for ENDTX (asynchronous API) - poor performance
- potential bytes dropping during preemption
- potential uart_tx returning -EBUSY when interrupted poll_out

On stm32f1 series, device pinctrl configuration could be modified
thanks to remapping capability.
Remapping allows to provide alternate pinctrl configuration to a
peripheral device and applies to all impacted pins.
So, specifically for stm32f1 series, apply remapping when required
before proceeding with pin configuration.
Additionally, because remapping is defined individually for each pin,
apply a function on pinctrl configuration to check remapping setting
coherency accorss pins.

Instantiate RTT UART instances from devicetree nodes instead of from
Kconfig symbols. While RTT is implemented using software, not hardware,
it is emulating a hardware device, and thus should be configured through
devicetree. This allows the simulated UART device to be selected via
devicetree aliases and chosen nodes.
The following devicetree snippet will instantiate RTT channels 0 and 2
as UART devices.
```
/ {
rtt0: rtt_terminal {
compatible = "segger,rtt-uart";
label = "rtt_terminal";
status = "okay";
};
rtt2: rtt_secondary {
compatible = "segger,rtt-uart";
label = "rtt_app_specific";
