msm: kgsl: Add Bind objects to dispatcher draw queue

kgsl_ioctl_gpu_sparse_command() is added to for user to
specify list of binds/unbinds for a memory entry
and syncpoints they depend on. If user specifies both
create a sync object for syncpoints and bind object for
binds/unbinds and add them to dispatcher draw queue. Sync
object should be inserted before the bind object in the
draw queue. Once the bind object reaches the head of
draw queue the corresponding binds/unbinds are performed.
kgsl_ioctl_gpu_sparse_command() only accepts commands from
context created with flag KGSL_CONTEXT_SPARSE, commands
from all other context types will return an error.
