[media] exynos4-is: Fix fimc-lite bayer formats
The 10-bit and 12-bit Bayer output formats supported by FIMC-LITE actually use 16 bits where the extra bits are padded with zeros. The patch corrects buffer allocation for these two formats by modifying the depth field. This prevents memory corruption by the output DMA due to insufficient buffer size.
