Subject: [PATCH 3/7] phy: sun4i-usb: a523: add support for the USB2 PHY

From: Mikhail Kalashnikov <iuncuim@...il.com>

Previously, USB PHY was compatible with D1 and did not require
separatedata options. But now we need to add a third PHY, which makes it
incompatible. The third PHY is used together with USB3/PCIe combophy with
DWC3 controller. In the BSP code, the third PHY requires a separate glue
driver, but it seems that it is not needed.
