[media] s5p-mfc: improve v4l2_capability driver and card fields
According to the V4L2 documentation the driver and card fields should be
used to identify the driver and the device but the s5p-mfc driver fills
those field using the platform device name, which in turn is the name of
the device DT node.
So not only the filled information isn't correct but also the same values
are used in all the fields for both the encoder and decoder video devices.
Before this patch:
Driver Info (not using libv4l2):
Driver name : 11000000.codec
Card type : 11000000.codec
Bus info : platform:11000000.codec
Driver version: 4.7.0
Driver Info (not using libv4l2):
Driver name : 11000000.codec
Card type : 11000000.codec
Bus info : platform:11000000.codec
Driver version: 4.7.0
After this patch:
Driver Info (not using libv4l2):
Driver name : s5p-mfc
Card type : s5p-mfc-dec
Bus info : platform:11000000.codec
Driver version: 4.7.0
Driver Info (not using libv4l2):
Driver name : s5p-mfc
Card type : s5p-mfc-enc
Bus info : platform:11000000.codec
Driver version: 4.7.0
