Manimaran A f8c8ee65be drivers: pinctrl: Microchip XEC PINCTRL glitch fix 
Glitches were observed if a GPIO pin was configured by
ROM to a non-default state and then Zephyr PINCTRL
reconfigured the pin. The fix involves using the correct
PINCTRL YAML output enable and state flags. Reading the
current spin state and reflecting into new pin configuration
if the pin is output and the drive low/high properties are
not present. We also take advantage of GPIO hardware reflecing
the alternate output value in the parallel output bit before
enabling parallel output mode. Interpret boolean flags with
both enable and disable as do not touch if neither flag is
present. We give precedence to enable over disable if both
flags mistakenly appear. Note, PINCTRL always clears the
GPIO control input pad disable bit.
