[PATCH] net: mdio: xgene: Fix unused xgene_mdio_of_match warning for !CONFIG_OF

[Rob Herring]

Commit a243ecc323b9 ("net: mdio: xgene: Use device_get_match_data()")
dropped the unconditional use of xgene_mdio_of_match resulting in this
warning:

drivers/net/mdio/mdio-xgene.c:303:34: warning: unused variable 'xgene_mdio_of_match' [-Wunused-const-variable]

The fix is to drop of_match_ptr() which is not necessary because DT is
always used for this driver (well, it could in theory support ACPI only,
but CONFIG_OF is always enabled for arm64).
