msm: kgsl: Detect long running IBs
When expired global timestamp is not progressing,
check if an IB is talking more than 2 seconds
with no update in GPU read pointer, IB1 base
IB1 size, IB2 base, IB2 size and detect it as a
long running IB. Invalidate the context of the IB
and do not attempt fault tolerance on this context.
