ASoC: Fixes for v4.0
As well as the usual collection of driver specific fixes there's a few
more generic things:
- Lots of fixes from Takashi for drivers using the wrong field in the
control union to communicate with userspace, leading to potential
errors on 64 bit systems.
- A fix from Lars for locking of the lists of devices we maintain,
mostly only likely to trigger during device probe and removal.
