The MDIO mux broadcom iproc can perform both C22 and C45 transfers.
Create separate functions for each and register the C45 versions using
the new API calls.

Apparently, in the c45 case, the reg value including the MII_ADDR_C45
bit is written to the hardware. Looks weird, that a "random" software
bit is written to a register. Florian is that correct? Also, with this
patch this flag isn't set anymore.
We should be masking the MII_ADDR_C45 bit because the MDIO_ADDR_OFFSET
only defines bits 0 through 20 as being read/write and bits above being
read-only. In practice, this is probably not making any difference or harm.
