Clayton Rayment 253761a0e6 net: xilinx: axiethernet: Enable dynamic MDIO MDC
MDIO spec does not require an MDC at all times, only when MDIO
transactions are occurring. This patch allows the xilinx_axienet
driver to disable the MDC when not in use, and re-enable it when
needed. It also simplifies the driver by removing MDC disable
and enable in device reset sequence.
