Subject: [PATCH v3 07/16] media: mtk-vcodec: venc: specify supported formats per-chip
Different chips have different supported bitrate ranges. Move the list
of supported formats to the platform data, and split the output and
capture formats into two lists to make it easier to find the default
format for each queue.
