[IrDA] setup dma fix

	o [CORRECT] Make ISA drivers depend on ISA. This is the consequence
		from David's change to setup_dma().
	o [CORRECT] Make new dongle drivers depend on sir-dev (they require it)
	o [FEATURE] Make old dongle drivers depend on irtty/irport
	o [FEATURE] irda-usb driver is no longer experimental
