Subject: [PATCH 2/4] arm64: dts: rockchip: enable USB A ports on ArmSoM
 Sige5

Enable the two USB type A ports (USB2 and USB3) present on the ArmSoM
Sige5 board.

Both ports use just one xHCI controller, with the USB 2.0 signals fed
off the same USB OTG PHY through an onboard hub. VBUS of both ports is
controlled by the same GPIO regulator (VCC_USBHOST in the schematics,
toggled by GPIO4 RK_PA6).
