====================
net: dsa: mv88e6xxx: move registers macros

This patchset brings no functional changes.

It is the first step of a cleanup renaming the chip header file and
moving the Register definitions _as is_ in their proper header files.

A following patchset will prefix them with the appropriate model
(MV88E6XXX_ or e.g. MV88E6390_) to respect an implicit namespace and
easily identify model subtleties in registers layout, as correctly done
in the newly added serdes.h header.
