[SCSI] aacraid: merge rx and rkt code
Received from Mark Salyzyn: The only real difference between the rkt and rx platform modules is the offset of the message registers. This patch recognizes this similarity and simplifies the driver to reduce it's code footprint and to improve maintainability by reducing the code duplication. Visibly, the 'rkt.c' portion of this patch looks more complicated than it really is. View it as retaining the rkt-only specifics of the interface.
