[PATCH v2 15/21] phy: sun4i-usb: Add support for the H616 USB PHY

The USB PHY used in the Allwinner H616 SoC inherits some traits from its various predecessors: it has four full PHYs like the H3, needs some extra bits to be set like the H6, and clears a different bit in the PMU_UNK1 register like the A100. Name all those properties in a new config struct and ass
