The SAM SoC requires that SUPC be configured to enable specific pins
to be used as wake-up sources. This add a new section denominated as
wakeup. In that section the pinmux will be used to store the correct
wkupX input to be used by the pinctrl driver to configure the gpio
and supc accordingly.
This update all pinconfigs, the pinctrl definitions, update the
documentation and expand the current test to cover the changes.

the missing documentation entry point with general guidelines. In
addition links the documentation on scripts and pinconfigs with

Add initial version of pinctrl script. It creates pinctrl definitions
from a well defined pinconfig yaml file. This file is filled with all
I/O multiplexing and considerations for all Atmel SAM SoCs. The auto
generated files produced by this script should be used inside a
<board>-pinctrl.dtsi file to define the pinctrl groups.
