[PATCH] pinctrl: Match DT helper types

[Rob Herring (Arm)]

The affected pinctrl drivers either check for the presence of a standard
property or read a property documented with an 8-bit cell encoding.
Using boolean or u32 helpers for those cases disagrees with the binding.

Use a presence helper for "gpio-ranges" and read
"microchip,spi-present-mask" with the u8 helper documented by the
binding.
