nwhitehorn 22459a6d41 Make tsec work with the device tree present on the RB800. The previous code 
assumed that the MDIO bus was a direct child of the Ethernet interface. It
may not be and indeed on many device trees is not. While here, add proper
locking for MII transactions, which may be on a bus shared by several MACs.
