Subject: [PATCH v6 13/17] 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 puts SIDDQ on a different bit like
the A100. Plus it needs this weird PHY2 quirk.

Name all those properties in a new config struct and assign a new
compatible name to it.
