Subject: [PATCH 2/4] arm64: dts: renesas: r9a09g057h44-rzv2h-evk: Enable USB3.0 PHYs and xHCI controllers

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@...renesas.com>

Enable the USB3.0 (CH0) and USB3.1 (CH1) host controllers on the RZ/V2H
Evaluation Kit. The CN4 stacked connector on the EVK provides access to
both channels, with CH0 corresponding to USB3.0 and CH1 to USB3.1.
