fimc-is: Adapt to latest changes DMA-mapping/IOMMU frameworks

This patch is a temporary workaround.

31-bit DMA mask is used to prevent overlapping with the Cortex-A5
reserved range. FIMC-IS CPU uses 0xe0000000-0xffffffff address
range for mapping peripheral devices, so those addresses must not
be used for memory buffers.
