boards/arm/s32k1xx/s32k118evb: Implement board support for LEDs and buttons. This is taken from the Freedom-K66f with has the same LED and button configuation as the S32K116EVB and uses the same GPIO IP.

Browse Source 
boards/arm/s32k1xx/s32k118evb/include/board.h:  Add LPUART0 pin disambiguation.

arch/arm/src/s32k1xx/hardware:  Add pin mux definitions for S32K116, 118, 142, 144, 146, and 148.

arch/arm/src/s32k1xx/s32k1xx_pin.c and .h:  Add support for PIDR register that disables a gneral purpose pin from acting as an input.

arch/arm/src/s32k1xx/s32k1xx_pin.c and .h:  The device does not support slew rate controls or open drain (on all the pins).  Only pins that are configured for a protocol that requires open-drain (e.g;, LPI2C, LPUART single-wire) will work in open-drain mode.
