[PATCH] ISA DMA Kconfig fixes - part 4 (irda)

 * net/irda/irda_device.c::irda_setup_dma() made conditional on
   ISA_DMA_API (it uses helpers in question and irda is usable on
   platforms that don't have them at all - think of USB IRDA, for
   example).
 * irda drivers that depend on ISA DMA marked as dependent on
   ISA_DMA_API
