[0/4] rockchip: Enable Ethernet controller on Radxa E20C

Message

The Rockchip RK3528 has two Ethernet controllers, one 100/10 MAC to be
used with the integrated PHY and a second 1000/100/10 MAC to be used
with an external Ethernet PHY.

This series add initial support for the Ethernet controllers found in
RK3528 and enable the LAN interface on Radxa E20C.

This only add a bare minimum gmac0 node for the 100/10 MAC and skip e.g.
parts to power on and off the integrated PHY in GMAC driver becayse I do
not have any RK3528 device that make use of gmac0.

This series depends on the "net: stmmac: dwmac-rk: Validate rockchip,grf
and php-grf during probe" cleanup series to ensure bsp_priv->grf can be
used. And possible also on the leds+buttons, sdio+sdmmc and sdhci series
for RK3528 for a clean apply.
