mdio: Export mdio.h to userland
The ID packing definitions are needed by userland and the register definitions may also be useful there. Do not export mdio_phy_id_{is_c45,prtad,devad}() as the use of bool is problematic and it's not that useful to export only a subset of these. Do not export MDIO_SUPPORTS_{C22,C45} directly; these flags are only exposed to userland through struct ethtool_cmd so they should be defined alongside that with appropriate names.
