msm: kgsl: Remove extra interrupts when setting MMU state
The interrupts added to the ringbuffer on PTFLUSH and TLBUPDATE
were causing a major increase in the number of interrupts from the GPU.
This was leading to increase in power and loss of performance. Add a check
to turn off IOMMU clocks when going to SLEEP.
