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.

Make it clear that mv88e6xxx_phy_ppu_{read,write} are an implementation
of the .phy_{read,write} operations, by renaming them with the mv88e6185
prefix, since 88E6185 it is the reference switch model supported in an
upstream board (ZII Dev Rev B), which makes use of them.
Distinguish the signatures of implementation specific and generic PHY
functions in the phy.h header.

Respect the implicit naming convention used in all register sets
specific files, by renaming the mv88e6xxx_ppu_* functions with the
mv88e6xxx_phy_* prefix.
This is simply a s/xxx_ppu/xxx_phy_ppu/ substitution.
