ASoC: OMAP ABE: BT backend as 16-bits stereo

Bluetooth data interface is connected to OMAP via McBSP and then to ABE.
ABE BT_VX ports require a low value for McBSP FIFO threshold (e.g. 1 for
mono, 2 for stereo), which has a side effect on latency. Since McBSP FIFO
stores each sample in a separate FIFO entry, using stereo instead of mono
halves the latency.

gcx: fix race conditions on suspend.

There was a race between the suspend thread waiting for idle and an
app thread attempting to push more into the gcqueue, which could
cause the suspend to block until the max retry count was reached.
Also, it was possible for the gccmdthread to notice gc320 is idle
while attempting to suspend and simultanesouly gc320 completed
processing some cmd buffers that require proper interrupt-aware
cleanup.

OMAPDSS: panel tc358765 initialization delay after power-on

This change adds delay for 100ms between powering on of display
panel tc358765 and its initialization. This delay is needed,
because time to time registers of the panel may be not initialized
directly after power-on. The value for delay was found
experimentally. Delay in tc358765_hw_reset() function (100ms) also
plays role.

If charge status set to POWER_SUPPLY_STATUS_NOT_CHARGING
capacity detection path is omitted.

Add this state to let capacity detection happen.

ASoC: ABE: Increase volume ramps for DMic's

Most digital microphones need about 10 ms to settle after setting bias
and clocks.  The OMAP DMic module is not able to set the clocks before
beginning the transfer, creating a full-scale pop at the beginning of
the transfer.

This patch works around this behavior by increasing the volume ramp
from 2ms to 50ms for DMic's.

gcx: fix mmu context switch issues.

On an mmu context switch, an mmu flush is required.

When the mmu is enabled after a power off, the mmu context
at the head of the cmd buffer queue is made current but the
cached current context was not updated so the next process
to try a commit would throw an l3 bus error.

gcx: validate dest rect after clipping

According to bltsville spec, rectangles should not be checked
for validity until clipping has been applied.  So we must clip
the dest rect before validating it.  Removed the error checking
from the generic rect converter macro.  Added error checking
specifically for clip rect and dest rect, post clipping. Proper
validity checking of other rects is TBD.
