msm: camera: isp: Pause the CRM timer in case of hardware errors

Przeglądaj źródła 
In the Case of CSID RX fetal errors, We disable rx path. Whenever
we get sof freeze after some time, we enable the path SOF
to do a health check of the sensor.
But we don’t get the SOFs and it gives the wrong impression that
the sensor is not streaming.

Notify crm driver to pause the timer in case of fatal hardware error
to not missled sof freez issue.
