Microchip XEC has been using the standard NS16550 driver.
Using the standard NS16550 driver requires extra HW programming
for XEC UART in board level and did not support XEC GIRQ interrupt
programming. We add an XEC specific driver and remove UART specific
register programming from the board level and implement interrupt
support. Also, by implementing a SoC specific driver we can add
driver PM in the future.

Scott Worley a10ce7561f soc: mchp: Deep sleep exit sequence update
Zephyr kernel masks interrupts before calling the SoC PM
sleep entry point. On the Cortex-Mx family this prevents
wake from peripheral interrupts. The SoC PM layer requires
interrupts to wake the SoC and must prevent the CPU from
vectoring to an interrup until PM exit. The SoC does this
by setting ARM NVIC PRIMASK to 1 and BASEPRI to 0. On
return to the kernel SoC sets PRIMASK to 0 allowing ISR's
to fire. In addition the MEC HW only clears its peripheral
sleep enables if the CPU vectors to an ISR. On wake we
clear the MEC PCR sleep control register which clears all
the peripheral sleep enables so peripherals will be active
before exiting the SoC PM layer.
