msm: kgsl: Reduce hang detection threshold for A610 GPU 



Hang detection threshold was increased to prevent false hang
detect issue happening because of a hardware issue. This is
not required on A610 GPU as hardware already has the fix.
Reduce the hang detection threshold value for A610 to make
sure recovery happens within reasonable time.
