Subject: [PATCH v2 0/4] venus: add support for 10 bit decoding

This series includes the changes to
  - add V4L2_PIX_FMT_P010 as supported decoder format.
  - consider dpb color format while calculating buffer
    size for dpb buffers.
  - update dpb and opb color format when bit depth
    changes is detected, also update preferred color
    format to P010 in this case.

With this series, divided the previous version [1] into
multiple patches as suggested in review comments.

This series depends on [2] which replaces the array index with enums.

changes since v1:
  use enums to assign formats in place of array index (konrad)
