ASoC: Changes to SOF kcontrol data set/get ops 

Merge series from Ranjani Sridharan <ranjani.sridharan@linux.intel.com>:

This set of patches deals with modifications to the signature of kcontrol
get/set data functions to make them more intuitive. The last patch deals
with initializing the binary control data size after boot up.
