Subject: [PATCH 5/7] media: mediatek: vcodec: Setting the supported h265 profile for each platform

The supported format type of different platforms are not the
same. Need to set the supported profile according to the chip name.

Set the maximum H265 codec profile for each platform.
The various mediatek platforms support different profiles for decoding,
the profile of the codec limits the capabilities for decoding.

With that you can add:
