asoc: codecs: Fix button interrupts issue in rouleur

Bläddra i källkod 
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.
