video: driver: enable session stability testing

Browse Source 
Enable session stability test support.

Clients can trigger session stability through debugfs as follows:
echo <trigger_val> > /d/msm_vidc/core/trigger_stability
u64 trigger_val provides:
    <payload><sub_client_id><stability_type>
    stability_type : 0-3 bits(one of the HFI_STABILITY_TYPE_*)
    sub_client_id  : 4-7 bits(1 - CCE, 2 - VSP, 3 - VPP, 4 - CPUSS)
    reserved       : 8-31 bits(Not used)
    payload        : 32-63 bits(depends on stability_type)

For e.x, to VCODEC_HUNG on CCE hardware module for 5 consequtive frames.
adb shell "echo 0x500000011 > /d/msm_vidc/core/trigger_stability".
