Many device pointers are initialized at compile and never changed. This
means that the device pointer can be constified (immutable).
Automated using:
```
perl -i -pe 's/const struct device \*(?!const)(.*)= DEVICE/const struct
device *const $1= DEVICE/g' **/*.c
```

When dealing with pm action 'suspend', driver applies device pinctrl sleep
state.
Using PM_DEVICE modes should allow to save more current consumption, and
applying pinctrl sleep state is one of the gains, but sleep state not being
available on a device is not a sufficient reason to block PM transition
to lower power mode.
If this pin state is not provided for the device, warn but don't block
pm transition. This will save some time to users setting up this feature
for the first time. Warning will give the opportunity to users to fine
tune their setup in a later step.

Zephyr kernel is dependent on trace.
Trace is dependent on segger rtt.
Segger rtt MUST NOT be dependent on zephyr kernel.
Move lock functions from header into c file to avoid circular
dependency. This fix needs an update of the segger repository.

Add workaround for development kits on which interface chip (segger chip)
is dropping bytes when they are sent in bursts. Issue has been seen on
DK which have multiple virtual com ports on the USB.
A workaround is adding periodic busy waits to introduce gaps in the
transmission.

The uart_pipe_isr() double-checks whether rx interrupt occured by
calling uart_irq_is_pending() first. Get rid of that function call since
it is redundant (i.e. nothing more is done or checked inside that
conditional).

The LPUART driver activates the "noise" error interrupt but
neglects to clear the error bit when the interrupt occurs. This
causes the device to freeze. Clear the "noise" status to avoid
the lockup and track instances of this as a UART_ERROR_PARITY.
