When a failure to stop a module in the pipeline is detected, the only
way to recover is to reset the ISP. However, as other users can be using
a different pipeline with other modules, the ISP can't be reset
synchronously with the error detection.

Mark the ISP as needing a reset when a failure to stop a pipeline is
detected, and reset the ISP when the last user releases the last
reference to the ISP.

Modify the omap3isp_pipeline_set_stream() function to record the new ISP
pipeline state only when no error occurs, except when stopping the
pipeline in which case the pipeline is still marked as stopped.

With the introduction of CSI2 support on sh-mobile, the host driver
switched to using v4l2_device_call_until_err() with grp_id == 0 to
call subdev operations on the sensor and the CSI2 subdev. However,
this has broken multi-client set ups like the one on migor, because
that way all operations get called on both clients. To fix this add
a grp_id and set it to the client private context.

When period interrupts are disabled, snd_pcm_update_hw_ptr0() compares
the current time against the time estimated for the current hardware
pointer to detect xruns.  The somewhat fuzzy threshold in the while loop
makes it possible that hdelta becomes negative; the comparison being
done with unsigned types then makes the loop go through the entire 263
negative range, and, depending on the value, never reach an unsigned
value that is small enough to stop the loop.  Doing this with interrupts
disabled results in the machine locking up.

To prevent this, ensure that the loop condition uses signed types for
both operands so that the comparison is correctly done.

Many thanks to Kelly Anderson for debugging this.
