[IRDA]: Support for Sigmatel STIR421x chip
This patch enables support for the Sigmatel's STIR421x IrDA chip.
Once patched with Sigmatel's firmware, this chip "almost" follows the
USB-IrDA spec. Thus this patch is against irda-usb.[ch].
The code has been tested by Nick Fedchik on an STIR4210 chipset based
dongle.
