[PATCH AUTOSEL 5.4 1/7] phy: sun4i-usb: Add support for the H616 USB PHY

[Sasha Levin]

From: Andre Przywara <andre.przywara at arm.com>

[ Upstream commit 0f607406525d25019dd9c498bcc0b42734fc59d5 ]

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.
