asoc: Add support for rouleur codec in machine driver

Add rouleur codec support in bengal machine driver
to create codec entry and invoke mbhc hs detect
functions for respective codecs. Correct the logic
for headset detection pull up current and
volatile registers for digital part of rouleur codec.
