media: mediatek: vcodec: Force capture queue format to MM21
[ Upstream commit 68c7df527657a9e962da7b5b9c0308557357d8dc ]
While the decoder can produce frames in both MM21 and MT21C formats, only
MM21 is currently supported by userspace tools (like gstreamer and libyuv).
In order to ensure userspace keeps working after the SCP firmware is
updated to support both MM21 and MT21C formats, force the MM21 format for
the capture queue.
This is meant as a stopgap solution while dynamic format switching between
MM21 and MT21C isn't implemented in the driver.
