Subject: [PATCH 13/23] intel_sst: move jack detection related configs to init
 time

From: Lu Guanqun <guanqun.lu@...el.com>

The old policy will not enable MIC2BIAS on Moorstown platform
by default, it's only enabled when the user selects HS_MIC as input source.
Therefore when user selects DMIC and then inserts the jack,
no interrupt will be generated to notify the driver about the
jack insertion event and to take action to auto mute the speaker.

The new policy will enable this bit by default,
then no matter what the output device is, an interrupt will be generated.

This behaviour is more likely what a user expects.
