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.

- *			    IMPORTANT NOTE
- *			    --------------
- *
- * As of kernel 2.5.20, this is the state of compliance and testing of
- * this driver (irda-usb) with regards to the USB low level drivers...
- *
- * This driver has been tested SUCCESSFULLY with the following drivers :
- *	o usb-uhci-hcd	(For Intel/Via USB controllers)
- *	o uhci-hcd	(Alternate/JE driver for Intel/Via USB controllers)
- *	o ohci-hcd	(For other USB controllers)
- *
- * This driver has NOT been tested with the following drivers :
- *	o ehci-hcd	(USB 2.0 controllers)
- *
- * Note that all HCD drivers do URB_ZERO_PACKET and timeout properly,
- * so we don't have to worry about that anymore.
- * One common problem is the failure to set the address on the dongle,
- * but this happens before the driver gets loaded...
- *
- * Jean II

- * Note :
- * Some of you may have noticed that most dongle have an interrupt in pipe

- * When we hang a Rx URB on the bulk in pipe, it generates some USB traffic
- * in every USB frame. This is unnecessary overhead.
- * The interrupt in pipe will generate an event every time a packet is

- * If we are connected (speed != 9600), we want to minimise latency, so

- * If we are not connected (speed == 9600), there is usually no Rx traffic,
- * and we want to minimise the USB overhead. In this case we should wait
- * on the interrupt pipe and hang the Rx URB only when an interrupt is
- * received.
