[media] s5p-jpeg: Initialize jpeg_addr fields to zero
JPEG codecs on Exynos4 and Exynos3250 SoCs utilize different number of planes for storing the raw image data, depending on the format of the image being processed. For the unused planes a random data was being written to the related registers. Regardless of the fact that this seemed not to be harmful, fix the issue for clarity reasons.
