Previously clock rates were set after initialization of timer.
Therefore the timer used the default extal1 clock rate (25MHz)
instead of the correct rate for this board (24MHz).

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.

Laurent's patch I sent because it was related
to ARCH_HAS_DMA_MMAP_COHERENT.
The remaining patch is sh_mobile_lcdc. I will remove ifdefs from the
patch and re-post it as a patch v4.
