sound fixes for 4.5-rc4

In this rc, we've got more volume than previous rc, unsurprisingly;
 the majority of updates in ASoC are about Intel drivers, and another
 major changes are the continued plumbing of ALSA timer bugs revealed
 by syzkaller fuzzer.  Hopefully both settle down now.
 
 Other than that, HD-audio received a couple of code fixes as well as
 the usual quirks, and various small fixes are found for FireWire
 devices, ASoC codecs and drivers.
