kernel: ar83xx: Add support for three GMAC's connection
We have IPQ8064 AP161 board which has three GMAC's
* RGMII x2
* SGMII x1.
The existing ar8327 driver does not have support for
three GMAC's connection, hence this change adds support
for the same. This has been verified on AP148 and AP161
board.
