[media] IR/lirc: further ioctl portability fixups

>From Joris van Rantwijk <jorispubl@xs4all.nl>:

	I tested lirc_serial and found that it works fine.
	Except the LIRC ioctls do not work in my 64-bit-kernel/32-bit-user
	setup. I added compat_ioctl entries in the drivers to fix this.

	While doing so, I noticed inconsistencies in the argument type of
	the LIRC ioctls. All ioctls are declared in lirc.h as having argument
	type __u32, however there are a few places where the driver calls
	get_user/put_user with an unsigned long argument.

	The patch below changes lirc_dev and lirc_serial to use __u32 for all
	ioctl arguments, and adds compat_ioctl entries.
	It should probably also be done in the other low-level drivers,
	but I don't have hardware to test those.

I've dropped the .compat_ioctl addition from Joris' original patch,
as I swear the non-compat definition should now work for both 32-bit
and 64-bit userspace. Technically, I think we still need/want a
in getting a reply to you).
