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.
