pinctrl: rockchip: Add RV1126 pinctrl support
RV1126 has five GPIOs groups - GPIO0 in PD_MMU and GPIO1-4 in PD_BUS. In GPIO0, up to Lower C group GPIO0_C[3:0] is part of PMU but rest of the groups from there are part of GRF. Added pinctrl support for RV1126 and the pull, drv and schmitt calculations are inferred from [1] authored by Jianqun Xu.
