fsl_diu: fix alignment error that caused malloc corruption
When aligning malloc()ed screen_base, invalid offset was added. This not only caused misaligned result (which did not cause hardware misbehaviour), but - worse - caused screen_base + smem_len to be out of malloc()ed space, which in turn caused breakage of futher malloc()/free() operation. This patch fixes screen_base alignment. Also this patch makes memset() that cleans framebuffer to be executed on first initialization of diu, not only on re-initialization. It looks correct to clean the framebuffer instead of displaying random garbage; I believe that was disabled only because that memset caused breakage of malloc/free described above - which no longer happens with the fix described above.
