[PATCH 3/4] phy: sun4i-usb: Add Allwinner R40 support

[Andre Przywara]

Since every Allwinner USB PHY seems to be slightly different from each
other, we need to add the compatible string and the respective data
structure to make it work on the R40/V40 SoC.
Nothing spectacular this time, just one less USB controller than the H3.
Copied from the Linux kernel.
