The 'pages' structure in the exynos gem buffer has been
removed. So we get the fix.smem_start from the first sgl
of the scatter gather table.

The BURST size of fimd is adjusted based on the number of bytes to be
read. This is calculated based on the overlay width and the number of
bits per pixel. There are three burst lengths supported - 4 words,
8 words and 16 words where each word is 8 bytes long.

contiguous
and calls dma_mmap_writecombine for mapping the buffer to user space.
dma_mmap_writecombine will be able to map a contiguous buffer as well
as non-contig buffer depending on whether an IOMMU mapping is created
for drm or not.

The exynos drm specific implementation of fb_mmap extracts the private
data from the fb_info and calls dma_mmap_attrs with the parameters
used while allocating the buffer.

large buffers.
Instead, we can just clone the sgt which was already created during
buffer allocation and create the new sgt. This is done by calling
'sg_clone_table'. This will be much faster than creating from pages.

The function dma_get_sgtable will allocate a sg table internally so
it is not necessary to allocate a sg table before it. The unnecessary
'sg_alloc_table' call is removed.
