[PATCH net-next 1/3] net: dsa: mv88e6xxx: provide a PHY setup helper

[Vivien Didelot]

Similarly to the VTU, PVT and ATU setup, provide a mv88e6xxx_phy_setup
helper which wraps mv88e6xxx_ppu_enable, so that no more PPU-related
functions are exposed outside of phy.c.

Thus make mv88e6xxx_ppu_enable static.
