Since commit f2d8b6917f3b ("media: v4l: ioctl: Set bus_info in
v4l_querycap()"), the V4L2 core provides a default value for the
bus_info field for platform and PCI devices. This value will match
the default value for media devices added by commit cef699749f37
("media: mc: Set bus_info in media_device_init()"). These defaults
are stable and device-specific.
Drop the custom capability bus_info from the mtk-vcodec decoder
driver, and use the defaults. This also fixes the long standing
issue where the media device used for the stateless decoder didn't
have its bus_info set, and would never match its accompanying video
device.
