media: subdev: fix compat_ioctl32
The adv7842 and si4713 drivers each define one private ioctl command that
are handled through the subdev_ioctl() helpers, but that don't work in
compat mode because this does not handle private ioctl commands.
The compat_ioctl32 callback for subdevs has outdated calling conventions,
but as there are no users of that, it is easy to change the function
pointer type and the caller to make it behave the same way as the normal
ioctl callback and hook in the two drivers that need no argument
conversion.
