ASoC: Fixes for v4.5

This is far too big a set of fixes for this late in the release cycle
but the overwhelming bulk is essentially the same simple fix from
Takashi for a cut'n'pasted 64 bit cleanliness issue in the userspace
interface where drivers were accessing things using the wrong element in
a union which worked OK on 32 bit platforms as the correct element
happened to be aligned the same way but with 64 bit platforms ABIs are
different and the two members of the union are laid out in different
places.  They aren't all tagged to stable since some of these chips have
vanishingly little chance of being used in 64 bit systems.

The other changes are:
 - A fix for Qualcomm devices to work on big endian systems.  The
   original change is actually correct but triggered a bug in regmap
   which is too invasive to fix for this cycle and can be worked around
   by just letting regmap pick the default.
 - A fix for the Samsung I2S driver locking which wasn't using IRQ safe
   spinlocks when it needed to.
 - A fix for the new Intel Sky Lake driver forgetting that C pointer
   arithmetic takes the type of the pointer into consideration.
 - A revert of a change to the FSL SSI driver that broke some systems.
 - A fix for the cleanup path of the wm9713 driver.
 - A fix for some incorrect register definitions in the ADAU17x1 driver
   that caused misclocking in some configurations.
 - A fix for the tracepoints for jack detection to avoid using an
   internal field of the core jack structure which is no longer present
   in all configurations.
 - A fix for another of the new Intel drivers which tried to write to a
   string literal.
