Subject: [PATCH net-next v1 0/5] Use MMD/C45 helpers

MDIO busses can perform two sorts of bus transaction, defined in
clause 22 and clause 45 of 802.3. This results in two register
addresses spaces. The current driver structure for indicating if C22
or C45 should be used is messy, and many C22 only bus drivers will
wrongly interpret a C45 transaction as a C22 transaction.

This patchset is a preparation step to cleanup the situation. It
converts MDIO bus users to make use of existing _mmd and _c45 helpers
to perform accesses to C45 registers. This will later allow C45 and
C22 to be kept separate.
