sunxi: phy: Add USB PHY support for Allwinner H6
The USB PHY used in the Allwinner H6 SoC has some pecularities (as usual), which require a small addition to the USB PHY driver: In this case the second PHY is PHY3, not PHY1, so we need to skip number 1 and 2 in the code. Just use the respective code from Linux for that.
