asoc: codecs: Avoid MBHC OverCurrentProtection.

Browse source 
In the existing code, Over Current Protection interrupt is enabled
 as part of MBHC insertion event handling.
This is causing audio mute on Stereo Headset randomly.
This OCP through MBHC is no more required as the
 Over Current/surge is handled in HW.
Removing the OCP enabling code to fix the issue.
