[PATCH 44/65] media: rockchip: rkvdec: Access v4l2_fh from file

[Jacopo Mondi]

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 fh_to_rkvdec_ctx() macro.
