phy: move fixed_phy MII register generation to a library Move the fixed_phy MII register generation to a library to allow other software phy implementations to use this code.

phy: separate swphy state validation from register generation Separate out the generation of MII registers from the state validation. This allows us to simplify the error handing in fixed_phy() by allowing earlier error detection.

phy: generate swphy registers on the fly Generate software phy registers as and when requested, rather than duplicating the state in fixed_phy. This allows us to eliminate the duplicate storage of of the same data, which is only different in format. As fixed_phy_update_regs() no longer updates register state, rename it to fixed_phy_update().
