[media] gsc-m2m: add device name sufix to bus_info capatiliby field



The driver doesn't set the device in the struct v4l2_capability bus_info
field so v4l2-compliance reports the following error for VIDIOC_QUERYCAP:

Required ioctls:
                fail: v4l2-compliance.cpp(537): missing bus_info prefix ('platform')
        test VIDIOC_QUERYCAP: FAIL

This patch fixes this by filling also the device besides the bus.
