net: stmmac: add support for hash table size 128/256 in dwmac4
1. get hash table size in hw feature reigster, and add support
for taller hash table(128/256) in dwmac4.
2. only clear GMAC_PACKET_FILTER bits used in this function,
to avoid side effect to functions of other bits.
stmmac selftests output log with flow control on:
ethtool -t eth0
The test result is PASS
The test extra info:
1. MAC Loopback 0
2. PHY Loopback -95
3. MMC Counters 0
4. EEE -95
5. Hash Filter MC 0
6. Perfect Filter UC 0
7. MC Filter 0
8. UC Filter 0
9. Flow Control 0
