[SCSI] aacraid: remove sparse warnings
This patch addresses the sparse -Wbitwise warnings that Christoph wanted
me to eliminate. This mostly consisted of making data structure
elements of hardware associated structures the __le* equivalent.
Although there were a couple places where there was mixing of cpu and le
variable math. These changes have been tested on both an x86 and ppc
machine running bonnie++. The usage of the LE32_ALL_ONES macro has been
eliminated.
