msm: vidc: add support for the bitstream_restrict flag

Adds support for the MFC core to add the bitstream_restrict flag in the
sps/pps for H264 codecs.  This allows for the decoder to determine how
many frames to buffer when decoding.

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.
