When a switch is attached to the mdio bus, the mdio bus can be used
while the interface is not open. If the IPG clock is not enabled, MDIO
reads/writes will simply time out. Add support for runtime PM to
control the clocks and other resources. Enable/disable the clocks
using runtime PM, with open()
