msm: kgsl: Make the GPU device aware of the next pending event
The adreno core needs to know what the next event pending for
any given context is so it can mark the interupt to be fired.
If this isn't done then some timestamps that don't have a
matching waittimestamp call won't fire an interrupt. This is
dangerous on the last interrupt/event before a context goes
away.
