net: stmmac: Check more MAC HW features for XGMAC Core 3.20
1. XGMAC Core does not have hash_filter definition, it uses
vlhash(VLAN Hash Filtering) instead, skip hash_filter when XGMAC.
2. Show exact size of Hash Table instead of raw register value.
3. Show full description of safety features defined by Synopsys Databook.
4. When safety feature is configured with no parity, or ECC only,
keep FSM Parity Checking disabled.
