[U-Boot] [PATCH] net: gmac_rockchip: Add support for pinctrl

[Romain Perier]

Currently, selecting state simple is done by the device driver model,
prior probing the driver. The problem is that it's done and called on
the pinctrl node with "gmac" as the "periph" struct udevice *. So
pinctrl-rk3288 is looking for an interrupt property that is not found,
and then gmac_config is never called.

This commits toggles the pinctrl on the right node from the probe
function of the driver.
