asoc: codecs: Add comparator autozeroing support for rouleur

Browse Source 
When current source mode is enabled, comparator auto
zeroing should be turned ON by HW. As rouleur codec HW
doesn't do this automatically, add this support
in SW to set the auto zero enable before FSM enable
and reset to auto once FSM is enabled.
Disable surge protection before ADC measurements
and change HPHL and HPHR thresholds while
identifying cross connection for proper
accessory identification.
