sbp2: provide helptext for CONFIG_IEEE1394_SBP2_PHYS_DMA and mark it experimental 



It appears I will not get it fixed overnight.

	  This builds sbp2 for use with non-OHCI host adapters which do not

	  support physical DMA or for when ohci1394 is run with phys_dma=0.

	  Physical DMA is data movement without assistence of the drivers'

	  interrupt handlers.  This option includes the interrupt handlers

	  that are required in absence of this hardware feature.



	  This option is buggy and currently broken on some architectures.

	  If unsure, say N.
