drm: switch drm_fb_memcpy_dstclip to accept __iomem dst
Not all archs have the __io_virt() macro, so cirrus can't simply convert pointers that way. The drm format helpers have to use memcpy_toio() instead. This patch makes drm_fb_memcpy_dstclip() accept a __iomem dst pointer and use memcpy_toio() instead of memcpy(). With that separating out the memcpy loop into the drm_fb_memcpy_lines() helper isn't useful any more, so move the code back into the calling functins.
