shmem_read_mapping_page() uses mapping_gfp_mask(mapping) as default gfp
mask. No reason to use shmem_read_mapping_page_gfp() directly if we want
the default behavior.

Commit 011c2282c74d changed the way refcounting on imported dma_bufs
works, and this hadn't been spotted while forward-porting Armada.
Reflect the changes in that commit into the Armada driver.

These can be 64-bit quantities, so fix them up appropriately.

This patch adds support for the pair of LCD controllers on the Marvell
Armada 510 SoCs. This driver supports:
- multiple contiguous scanout buffers for video and graphics
- shm backed cacheable buffer objects for X pixmaps for Vivante GPU
acceleration
- dual lcd0 and lcd1 crt operation
- video overlay on each LCD crt via DRM planes
- page flipping of the main scanout buffers
- DRM prime for buffer export/import
This driver is trivial to extend to other Armada SoCs.
Included in this commit is the core driver with no output support; output
support is platform and encoder driver dependent.
