[media] s5p-mfc: Set DMA_ATTR_ALLOC_SINGLE_PAGES
We do video allocation all the time and we need it to be fast. Plus TLB
efficiency isn't terribly important for video.
That means we want to set DMA_ATTR_ALLOC_SINGLE_PAGES.
See also the previous change (commit 14d3ae2efeed "ARM: dma-mapping: Use
DMA_ATTR_ALLOC_SINGLE_PAGES hint to optimize allocation").
[m.szyprowski: rebased patch onto v4.9-rc1 and adapted changes
to latest videbuf2 changes, this simplifies code changes to
only set proper dma attribute flag and comment the reason
for it, added commit id of arch/arm/mm patch]
