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.

Current source mode in rouleur does not work
properly leading to issues in button interrupts
and fake electrical removal interrupts.
Enable pull up mode instead of current source
mode to fix these issues. Modify the headset
max vref voltage to 1.7 volts and micbias
calculation logic.

Playback pauses during aux cable insertion as removal of
cable is reported followed by insertion. Report removal
of current cable only when headset connected to other end
of extension cable and not lineout.

In wcd_mbhc_adc_hs_rem_irq when hph_on bit is set
both left and right channel should get enabled. But we
enable left channel first, disable left ch and enable right channel.
Fix this to enable both left and right channel.

When detecting special headset, vref for special headset is
set based on headset threshold reference 1800mv or based on
regular micbias settings from device tree. Scale threshold
reference as per the special headset micbias voltage.

Comparison of headset threshold during special headset detection is
not proper. This results in to improper detection of special headset
and recording usecase failure on special headset. Fix the special
headset detection issue by adding proper check condition while selection
of headset threshold from device tree.
