Add support for GPIO controller from RDA Micro. This GPIO controller
is an in house IP, developed by RDA Micro (now Unisoc) for the use in
RDA88* series of SoCs. There are multiple GPIO ports present in all SoCs,
each capable of addressing 32 GPIOs. But only first 8 pins have the
interrupt capability.
