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: Don't hold process list global mutex in process private create

Don't hold process list global mutex for long. Instead make
use of process specific spin_lock() to serialize access
to process private structure while creating it. Holding
process list global mutex could lead to deadlocks as other
functions depend on it.
