V4L/DVB: IR: put newly ported streamzap driver in proper home

Moves drivers/staging/lirc/lirc_streamzap.c to

- * Streamzap Remote Control driver
- *
- * Copyright (c) 2005 Christoph Bartelmus <lirc@bartelmus.de>
- * Copyright (c) 2010 Jarod Wilson <jarod@wilsonet.com>
- *
- * This driver was based on the work of Greg Wickham and Adrian
- * Dewhurst. It was substantially rewritten to support correct signal
- * gaps and now maintains a delay buffer, which is used to present
- * consistent timing behaviour to user space applications. Without the
- * delay buffer an ugly hack would be required in lircd, which can
- * cause sluggish signal decoding in certain situations.
- *
- * Ported to in-kernel ir-core interface by Jarod Wilson
- *
- * This driver is based on the USB skeleton driver packaged with the
- * kernel; copyright (C) 2001-2003 Greg Kroah-Hartman (greg@kroah.com)
