[PATCH] [media] coda: add missing header dependencies
We get 1 warning when building kernel with W=1:
drivers/media/platform/coda/coda-h264.c:21:5: warning: no previous prototype
for 'coda_h264_padding' [-Wmissing-prototypes]
In fact, this function is declared in drivers/media/platform/coda/coda.h,
so this patch adds missing header dependencies.
