Subject: [PATCH v3] media: cedrus: Add support for VP8 decoding
VP8 in Cedrus shares same engine as H264.
Note that it seems necessary to call bitstream parsing functions,
to parse frame header, otherwise decoded image is garbage. This is
contrary to what is driver supposed to do. However, values are not
really used, so this might be acceptable. It's possible that bitstream
parsing functions set some internal VPU state, which is later necessary
for proper decoding. Biggest suspect is "VP8 probs update" trigger.

Changes in v3:
- addressed comments from Ezequiel Garcia - new comments,
using new macros from VP8 UAPI, new function for waiting
on bit to be set
Changes in v2:
- rebased on top of current linux-media master branch
NOTE: This now depends on following patch:
