ASoC: Fixes for v3.13

A smattering of fixes here, some core ones for the rate combination
issues for things other than simple bitmasks, for readback of byte
controls and for updating the power of value muxes plus a bunch of
driver fixes of varying severity.

The warning fix in the i.MX FIQ driver is fixing a warning introduced
by a previous fix.
