kgsl: switch back to allocating from highmem
Commit 344c3acdd8e436ccf7c4726422e2af85f5fb5a0a switched kgsl to allocating
from highmem in page-sized chunks. While this reduced pressure on highmem, it
may have increased pressure on lowmem to the point where lowmemorykiller
activity due to GFP_KERNEL requests rose.
b/19236185 Phone runs for about day, then apps start getting constantly killed
by lowmemorykiller
