msm: kgsl: Issue conditional interrupts on internal submissions
Waittimestamp calls require interrupts to check if a timestamp
has passed. The lack of these interrupts was causing waittimestamp
to wait longer than expected since the interrupts were less frequent.
Cause the conditional interrupts to be issued faster by allowing
internal command submissions to issue them.
