Subject: net: stmmac: Delete dead code for MDIO registration
Patch-mainline: v4.14-rc1
Git-commit: 5e369aefdce4818c8264b81d3436eccf35af561e
References: bsc#1119113 FATE#326472

This code is no longer used, the logging function was changed by commit
fbca164776e4 ("net: stmmac: Use the right logging function in stmmac_mdio_register").
It was previously showing information about the type of the IRQ, if it's
polled, ignored or a normal interrupt. As we don't want information loss,
I have moved this code to phy_attached_print().

Fixes: fbca164776e4 ("net: stmmac: Use the right logging function in stmmac_mdio_register")
