arm64: dts: rockchip: px30: Add 12ma strength for rmii mac_refclk pin
If the mac_refclk is provided from mac controller, the pin of mac_refclk
needs to setup 12ma strength, or the signal is not good.
If the mac_refclk is provided from phy, the pin of mac_refclk needs not
to setup 12ma strength, the phy would do it.
