[PATCH v2 4/4] fbdev: sh_mobile_lcdc: use dma_mmap_coherent if available

Hi Eiraku-san,

fb_mmap() implemented in fbmem.c uses smem_start as the physical
address of the frame buffer.  In the sh_mobile_lcdc driver, the
smem_start is a dma_addr_t that is not a physical address when IOMMU is
enabled.  dma_mmap_coherent() maps the address correctly.  It is
available on ARM platforms.
