The four platforms that set the field to a register address all use an address higher than 0x7fffffff, which is thus considered by the driver as invalid. The feature is thus never used, remove it. The feature could be implemented properly in the future using the pinctrl and GPIO APIs if desired. While at it, don't set the field to SCIx_NOT_SUPPORTED (-1) either, leaving it unset leads to the same result. This will allow removing the SCIx_NOT_SUPPORTED macro.
