The MCUX platform always uses pinctrl, there's no need to keep extra
macrology around pinctrl. Also updated driver's Kconfig options to
`select PINCTRL` (note that some already did).

Update pwm 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.
