This version should address all comments from Luis. In the last patch
the fw_lock dependency is dropped. This only works if we garantee not
to race between the reader and the writer side in combination in going
to sleep and waking up. So here that should now be a good argument for
swait :)


changes since v2:
- more splitting out
- first patch factors out all the bit ops into fw_status
- second patch gets rid of the bit ops
- third get rid of fw_lock by using swait

changes since v1:
- moved swait change into its own patch
- added ifdef section for FW_LOADER_USER_HELPER_FALLBACK
- updated commit message highlighting the mutex usage drop a bit
