[U-Boot] [PATCH V2 10/10] ARM: renesas: Enable R8A66597 USB host on GR Peach

[Marek Vasut]

Enable USB host support on GR Peach board.

To use USB host on GR Peach, it might be necessary to solder JP3 header
onto the board first and then short it. Shorting JP3 is mandatory to let
the U5 regulator to supply VBUS to the CN3 USB port.
