Use inbnd/outbnd instead of inb/outb which make one think of byte  
level io accessors.

As I look at this I don't think this is the correct API.  I think we  
should be using the DMA mapping API to hide these details.  The  
concept of mapping like this seems to be more a function of FSL's  
Address translation/mapping unit (ATMU) than anything specific to the  
RIO bus standard.
