fixed_phy_add() has a number of problems/disadvantages: - It uses phy address 0 w/o checking whether a fixed phy with this address exists already. - A subsequent call to fixed_phy_register() would also use phy address 0, because fixed_phy_add() doesn't mark it as used. - fixed_phy_add() is used from platform code, therefore requires that fixed_phy code is built-in. Now that for the only two users (coldfire/5272 and bcm47xx) fixed_phy creation has been moved to the respective ethernet driver (fec, b44), we can remove fixed_phy_add().
