Subject: [PATCH v2,6/7] media: mediatek: vcodec: Set the supported vp9 level for each platform

Set the maximum VP9 codec level for each platform.
The various mediatek platforms support different levels for decoding, the
level of the codec limits among others the maximum resolution, bit rate,
frame rate and compression rate for the decoder.
