arm64: dts: allwinner: h6: tanix-tx6: Add PIO power supplies 



While there is no publicly available schematic of this board, it's not
hard to determine voltage of GPIO port C, D and G (only ones which can
be set).

Port C and G are used for MMC/SDIO communication, so they use 1.8 V
power supply. It's not clear if port D is even used, but if it is, it's
pretty safe to assume it uses 3.3 V power supply. Value read from PIO
Group Withstand Voltage Mode Select register from within pre-installed
Android agrees with that assesment.
