net-next: mediatek: add fixed-phy support

blogic · davem330 · commit 0c72c50f6f93 · 2016-06-03T19:54:16.000-04:00
The MT7623 SoC has a builtin gigabit switch. If we want to use it, GMAC1
needs to be configured using a fixed link speed and flow control settings.
The easiest way to do this is to used the fixed-phy driver, allowing us to
reuse the existing mdio polling code to setup the MAC.
