sound fixes for 4.14 

Unfortunately we still have received a significant amount of changes
 at the late stage, but at least all are small and clear fixes.
 
 There are two fixes for ALSA core stuff, yet another timer race fix
 and sequencer lockdep annotation fix.  Both are spotted by syzkaller,
 and not too serious but better to paper over quickly.
 
 All other commits are about ASoC drivers, most notably, a revert of
 RT5514 hotword control that was included in 4.14-rc (due to a kind of
 abuse of kctl TLV ABI), together with topology API fixes and other
 device-specific small fixes that should go for stable, too.
