The function storvsc_dev_remove() already deals with draining of
the outstanding I/O. Cleanup blkvsc_remove() keeping this in mind.

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.

When the corresponding output device is not in playback, we can hear a little
noises.
Fix it by powering on the device only when it's in playback.

Root cause is, the driver is reporting 32-bit capture capability
that is not supported by the MRST hardware. So the dsnoop plugin
end up requesting 32-bit capture which fails.

Without this patch, the change of output/input device can't be reflected
correctly. The mismatch reflects insane design, and should be fixed when
switching to the ASoC framework.

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.

This patch fixes the below issues w.r.t jack implementation
a) The current jack implementation in driver is implemented
in intelmid.c. It has moved to vendor files for better managebility
b) Cleaned up jack reporting per upstream comments
c) Implemented jack for msic, added code to read adc and deduce jack
type based on mic bias
d) Support detection of american headset
