This patchset dynamically enable MDIO interface. The background for this change is coming from Cadence GEM controller(macb) in which MDC is active only during MDIO read or write operations while the PHY registers are read or written. It is implemented as an IP feature.
For axiethernet as dynamic MDC enable/disable is not supported in hw we are implementing it in sw. This change doesn't affect any existing functionality.
