[SCSI] qla2xxx: Add ISP24xx ISR routines.
Add ISP24xx ISR routines. Add appropriate glue-code for ISP24xx support -- this included generalizing some of the core handling routines (qla2x00_async_event() [pull-up retrieval of mailbox values] and qla2x00_status_entry()]. Fixup 2100/2300 ISRs to handle the new conventions. Signed-off-by: Andrew Vasquez <andrew.vasquez@qlogic.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
