The v4l2_fh associated with an open file handle is now guaranteed
to be available in file->private_data, initialised by v4l2_fh_add().
Access the v4l2_fh, and from there the driver-specific structure,
from the file * in all ioctl handlers.
While at it, remove the now unused mxc_jpeg_fh_to_ctx() macro.
