* Deprecate encoder drain mode, better document decoder drain mode
* Various documentation fixes and new overviews about en- and
decoding to help with the basic concepts
* Add note about the current state of i.MX8m plus support
* New functions:
imx_vpu_api_is_color_format_rgb()
imx_vpu_api_vp8_profile_number()
imx_vpu_api_vp8_partition_count_number()
imx_vpu_api_vp9_profile_number()
imx_vpu_api_enc_set_frame_rate()
