ASoC: Updates for v4.16
Some more updates for v4.16, the big things here are the ST DFSDM driver
and the IIO patches required to support that and even more in the
neverending series of code quality improvements for x86, including
Pierre's work to improve the Kconfig. The unused SN95031 driver and
associated board support are also removed, they haven't been buildable
for a considerable time without anyone noticing.
