ASoC: Fixes for v4.11

Browse Source 
A few last minute fixes for v4.11, the STI fix is relatively large but
 driver specific and has been cooking in -next for a little while now:
 
  - A fix from Takashi for some suspend/resume related crashes in the
    Intel drivers.
  - A fix from Mousumi Jana for issues with incorrectly created
    enumeration controls generated from topology files which could cause
    problems for userspace.
  - Fixes from Arnaud Pouliquen for some crashes due to races with the
    interrupt handler in the STI driver.
