The reason why I put the value NOT macro define here is the header file is put
in arch/arm64/boot/dts/freescale/ folder rather than include/dt-binding/pinctrl/,
so when using macro define, need to include the header file using absolute path
arch/arm64/boot/dts/freescale/, I think it is NOT that good, so I put the value here directly.
Anson.
