The change log does not say anything about refactoring
mv88e6xxx_ppu_disable() and mv88e6xxx_ppu_enable() into one function.
That should be in separate patch. Also, i don't see much value in this
refactoring. The names mv88e6xxx_ppu_disable() and
mv88e6xxx_ppu_enable() are much clearer than having one function which
takes a bool.
