msm: display: command mode panel release fence

For command mode panel, release fence should be signaled after the buffer is
sent to the panel.  For performance consideration, allow one more commit to be
queued.  Keep the second kick off as short as enough.

msm: mdp: Change msmfb kworker to kthread

This worker can be a longer running task depending on the number
of frames queued, hence change it to a thread.

msm: kgsl: Use the kmalloc/vmalloc trick for the sharedmem page array

It was previously assumed that most GPU memory allocations would be
small enough to allow us to fit the array of page pointers into one
or two pages allocated via kmalloc.  Recent reports have proven
those assumptions to be wrong - allocations on the order of 32MB will
end up trying to get 8 pages from kmalloc and 8 contiguous pages
on a busy system are a rare beast indeed.

So use the usual kmalloc/vmalloc trick instead - use kmalloc for the
page array when we can and vmalloc if we can't.
