From: Adrian Bunk <bunk-DgEjT+Ai2ygdnm+yROfE0A@public.gmane.org>

This patch removes IrPORT and the old dongle drivers (all off them
have replacement drivers).

- *     This driver is ment to be a small half duplex serial driver to be
- *     used for IR-chipsets that has a UART (16550) compatibility mode. 
- *     Eventually it will replace irtty, because of irtty has some 
- *     problems that is hard to get around when we don't have control
- *     over the serial driver. This driver may also be used by FIR 
- *     drivers to handle SIR mode for them.
