[PATCH v7 8/9] arm64: dts: renesas: r9a08g046l48-smarc: Add USB2.0 Host support

From: Biju Das <[email protected]>

Enable USB2.0 Host on the RZ/G3L SMARC board (r9a08g046l48-smarc).

Port 0 (ehci0, ohci0, usb2_phy0) is configured as OTG with
usb0_pins pinmux (USB20_OVRCUR, USB20_VBUSEN) and usb0_vbus_otg
as the VBUS supply. Port 1 (ehci1, ohci1, usb2_phy1) is configured
as host-only with usb1_pins pinmux (USB21_OVRCUR, USB21_VBUSEN),
usb1_vbus_otg as the VBUS supply, and renesas,no-otg-pins set to
indicate no OTG pin routing. The phyrst USB PHY reset controller is
also enabled.
