Merge branch 'net-stmmac-rk-use-phy_intf_sel_x'

Russell King says:

====================
net: stmmac: rk: use PHY_INTF_SEL_x

This series is a minimal conversion of the dwmac-rk huge driver to use
PHY_INTF_SEL_x constants.

Patch 2 appears to reorder the output functions making diffing the
generated code impossible.
