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.
