[media] s5p-jpeg: Fix sysmmu page fault

Browse source

This patch fixes jpeg sysmmu page fault on Exynos4x12 SoCs.
During encoding Exynos4x12 SoCs access wider memory area
than it results from Image_x and Image_y values written to
the JPEG_IMAGE_SIZE register. In order to avoid sysmmu page
fault apply proper output buffer size alignment.
