This spin lock is potentially acquired from interrupt context.
Ensure that the interrupts are blocked whenever the lock is held.
The current code was not consistent with regards to blocking
interrupts - the same lock would be acquired without blocking
interrupts in some instance while the interrupts would be blocked
in other instances. Fix this potential deadlock problem.

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.
