net: stmmac: xgmac: Disable MMC interrupts by default

Browse Source 
MMC interrupts were being enabled, which is not what we want because it
will lead to a storm of interrupts that are not handled at all. Fix it
by disabling all MMC interrupts for XGMAC.

Fixes: b6cdf09f51c2 ("net: stmmac: xgmac: Implement MMC counters")
