ASoC: Intel: avs: New boards and fixes to existing

Merge series from Cezary Rojewski <cezary.rojewski@intel.com>:

Series adds support for two boards: es8336 and rt5663. The former is
utilized by some KBL-based tablets whereas the latter unlocks
Chromebooks with rt5663 i2c codecs.

As existing implementation of es8336 (es8316.c) codec driver is not
prepared to cope with KBL-based platforms, couple of small,
clock-related changes precede anything avs-driver related.

The tail of patchset cleans up existing implementation of rt5682.
