NET: Move MDIO regs out of TSEC Space
Moved the mdio regs out of the tsec structure,and provided different offsets for tsec base and mdio base so that provision for etsec2.0 can be provided. This patch helps in providing the support for etsec2.0 In etsec2.0, the MDIO register space and the etsec reg space are different. Also, moved the TSEC_BASE_ADDR and MDIO_BASE_ADDR definitons into platform specific files.
