[PATCH u-boot v2019.04-aspeed-openbmc v2] pinctrl: ast2400: add support for RGMII1 and RGMII2

[Zev Weiss]

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