We currently don't have any code configuring interface mode in ath79, meaning that we relies on bootloader to set the correct interface mode. This patch added code to set interface correctly so that everything works even if bootloader configures it wrong.(e.g. on WNDR3800 u-boot set the second GMAC mode to RMII but it should be RGMII.) Introduced "qca,mac-idx" for the difference in MII_CTRL register value. Signed-off-by: Chuanhong Guo <gch981213@gmail.com>
