Subject: [PATCH 5/7] arm64: dts: allwinner: a523: add USB3.0 phy node

From: Mikhail Kalashnikov <iuncuim@gmail.com>

After adding the phy driver, we can also add phy node. In addition to the
clk and reset lines, the power domain PD_PCIE is declared in this node
according to the bsp dtb. So let's mention it. 
Currently, phy driver does not support role selection and only works in
USB3.0 mode.
