Update pinctrl drivers to use DT_HAS_<compat>_ENABLED Kconfig symbol
to expose the driver and enable it by default based on devicetree.
We remove 'depend on' Kconfig for symbols that would be implied by
the devicetree node existing.

Config pwm open-drain mode without enabling STORE_REG. This CL
collects all active PWM's base address and related index in an
array. Then, pinctrl driver configs its open-drain mode by
finding the corresponding 'channel' index.

This CL is the initial version for npcx pinctrl driver and introduces
pinctrl nodes for both IO-pads and peripheral devices for each npcx
series. Users can set pin configuration via these nodes in the board
layout DT file. It also wraps all configurations related to pin-muxing
in pinctrl_soc.h. Regarding the other pin properties, we will implement
them later.
