i40e: Use DECLARE_BITMAP for flags field in i40e_hw

Convert flags field in i40e_hw from u64 to bitmap and its usage
to use bit access functions and rename the field to 'caps' as
this field describes capabilities that are set once on init and
read many times later.

Changes:
- Convert "hw_ptr->flags & FLAG" to "test_bit(FLAG, ...)"
- Convert "hw_ptr->flags |= FLAG" to "set_bit(FLAG, ...)"
- Convert "hw_ptr->flags &= ~FLAG" to "clear_bit(FLAG, ...)"
- Rename i40e_hw.flags to i40e_hw.caps
- Rename i40e_set_hw_flags() to i40e_set_hw_caps()
- Adjust caps names so they are prefixed by I40E_HW_CAP_ and existing
  _CAPABLE suffixes are stripped
