media: coda: jpeg: support optimized huffman tables

Browse source

Each jpeg can have the huffman tables optimized for its specific content
meaning that the table lenghts and values don't match the standard table
of substitutions so there's no reason to hardcode and expect the standard
lengths, otherwise we just end up rejecting optimized jpegs altogether.

Tested on CODA960.
