gpio: renesas: Add R-Car Gen5 support
Add support for the GPIO controller block in the R-Car Gen5 SoC family.
The GPIO controller has a General Input Enable Register (INEN), whose
reset state is to have all input disabled. The GPIO controller also has
updated offsets for its control registers. U-Boot uses three registers,
INDT, POSNEG, INEN, which have updated offsets, those are handled by the
driver.
