Hi, 

I committed changes to ncr53c9x driver to support sun's fas controller
on sparc64 machines. I ran it for a pretty long time but on limited
variety of scsi devices. I was unable to make dmaselect works
with fas so I needed to transform this feature from global to per
controller and I added it  as NCR_F_DMASELECT,  I also removed 
ncr53c9x_dmaselect global variable from the driver so I'm going
to correct depending drivers to sc_features use.  HOpe I have not
broke much. Any feedback appreciated.

Thanks for all helped with writing and testing,
	Andrey
