Icenowy Zheng 5f19c93021 sunxi: set PIO voltage to hardware-detected value on startup on H6 ... The Allwinner H6 SoC has a register to set the PIO banks' voltage. When it mismatches the real voltage supplied to the VCC to the PIO supply, the PIO will work improperly. The PIO controller also has a register that contains the status of each VCC rail of the PIO supplies, and it has the same definition with the configuration register. so we can just copy the content of this register to the configuration register at startup, to ensure the configuration is correct at startup stage.
