i40e: Use DECLARE_BITMAP for flags and hw_features fields in i40e_pf

Convert flags and hw_features fields from i40e_pf from u32 to
bitmaps and their usage to use bit access functions.

Changes:
- Convert "pf_ptr->(flags|hw_features) & FL" to "test_bit(FL, ...)"
- Convert "pf_ptr->(flags|hw_features) |= FL" to "set_bit(FL, ...)"
- Convert "pf_ptr->(flags|hw_features) &= ~FL" to "clear_bit(FL, ...)"
- Rename flag field to bitno in i40e_priv_flags and adjust ethtool
  callbacks to work with flags bitmap
- Rename flag names where '_ENABLED'->'_ENA' and '_DISABLED'->'_DIS'
  like in ice driver
