[PATCH u-boot v2019.04-aspeed-openbmc] pinctrl: ast2400: add support for RGMII2

[Zev Weiss]

The bits configured by this pinctrl group are set to the same values
as their reset defaults, so RGMII2 functionality would likely work
anyway, but it seems good to make it explicit instead of relying on
that.
