media: hantro: Use core-generated bus_info value
The Hantro driver uses a hardcoded value for the bus_info field in the media device and |struct v4l2_capability|. This worked well when there was just one device. However with the iMX.8 series we are now seeing two Hantro blocks on the same chip. The static bus_info is no longer sufficient for differentiating devices. 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 static bus_info values from the hantro driver and use the defaults.
