[media] exynos4-is: Fix driver name reported in vidioc_querycap
Originally struct v4l2_capability driver and card name was filled with name of the platform device. After switching to the device tree the device names have changed and now are 4 different driver names reported, depending on the video device opened. So instead of e.g. "exynos4-fimc" there is now one of: 11800000.fimc, 11810000.fimc, 11820000.fimc, 11830000.fimc. Fix this by using dev->driver_name, rather than platform device name. A common vidioc_querycap function is created for both M2M and capture video node. This fixes any breakage at user space should any application/library rely on the driver's name.
