drm/msm: Support pgtable preallocation
Introduce a mechanism to count the worst case # of pages required in a
VM_BIND op.
Note that previously we would have had to somehow account for
allocations in unmap, when splitting a block. This behavior was removed
in commit 33729a5fc0ca ("iommu/io-pgtable-arm: Remove split on unmap
behavior)"
