net: xgene: Fix unused xgene_enet_of_match warning for !CONFIG_OF

Commit b037711 ("net: ethernet: Use device_get_match_data()") dropped
the unconditional use of xgene_enet_of_match resulting in this warning:

drivers/net/ethernet/apm/xgene/xgene_enet_main.c:2004:34: warning: unused variable 'xgene_enet_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).
