irda: move drivers/net/irda to drivers/staging/irda/drivers

Move the irda drivers from drivers/net/irda/ to
drivers/staging/irda/drivers as they will be deleted in a future kernel
release.

- * Filename:      w83977af_ir.c
- * Version:       1.0
- * Description:   FIR driver for the Winbond W83977AF Super I/O chip
- * Status:        Experimental.
- * Author:        Paul VanderSpek
- * Created at:    Wed Nov  4 11:46:16 1998
- * Modified at:   Fri Jan 28 12:10:59 2000

- *     If you find bugs in this file, its very likely that the same bug
- *     will also be in pc87108.c since the implementations are quite
- *     similar.
- *
- *     Notice that all functions that needs to access the chip in _any_
- *     way, must save BSR register on entry, and restore it on exit.
- *     It is _very_ important to follow this policy!
