Series net: extend the netdev_features_t | expand

Commit Message

shenjian (K) Sept. 29, 2021, 3:52 p.m. UTC
Use netdev_feature_xxx helpers to replace the logical operation
for netdev features.

Changes the type of "hw_features" of struct mtk_soc_data to "u64",
for it is initialized in the variable definition stage, avoid
compile issue when change the type of "netdev_features_t" to
"unsigned long *".
