This patch adds a list of supported codecs per device type which is used to determine the allowed pixel formats and maximum frame sizes depending on the possible codecs. It allows frame sizes larger than 720 x 576 on CODA7 and adds support for the YVU420 (planar YUV 4:2:0 with switched Cb and Cr) format. Other uncompressed formats that could be added in the future are the chroma interleaved NV12 and NV21 formats and the multiplanar variants YUV420M, YVU420M, NV12M, and NV21M. Further, rawstreamon is renamed to streamon_out and compstreamon is renamed to streamon_cap in preparation for decoding support. The maximum encoded frame buffer size is increased to 1 MiB. Instead of tracking inst_type and codec across S_FMT calls, set the codec and inst_type in start_streaming.
