[media] s5p-mfc: set capablity bus_info as required by VIDIOC_QUERYCAP
The driver doesn't set the struct v4l2_capability bus_info field so the
v4l2-compliance tool reports the following errors for VIDIOC_QUERYCAP:
Required ioctls:
VIDIOC_QUERYCAP returned 0 (Success)
fail: v4l2-compliance.cpp(304): string empty
fail: v4l2-compliance.cpp(528): check_ustring(vcap.bus_info, sizeof(vcap.bus_info))
test VIDIOC_QUERYCAP: FAIL
This patch fixes by setting the field in VIDIOC_QUERYCAP ioctl handler:
Required ioctls:
VIDIOC_QUERYCAP returned 0 (Success)
test VIDIOC_QUERYCAP: OK
