>
> 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
