phylib: rework to prepare for OF registration of PHYs
This patch makes changes in preparation for supporting open firmware device tree descriptions of MDIO busses. Changes include: - Cleanup handling of phy_map[] entries; they are already NULLed when registering and so don't need to be re-cleared, and it is good practice to clear them out when unregistering. - Split phy_device registration out into a new function so that the OF helpers can do two stage registration (separate allocation and registration steps).
