net: mvmdio: print warning when orion-mdio has too many clocks

Browse source

Print a warning when device tree specifies more than the maximum of four
clocks supported by orion-mdio. Because reading from mdio can lock up
the Armada 8k when a required clock is not initialized, it is important
to notify the user when a specified clock is ignored.
