[SCSI] hptiop: add more adapter models and other fixes 



Most code changes were made to support adapters based on Marvell IOP, plus some
other fixes.

- add more PCI device IDs
- support for adapters based on Marvell IOP
- fix a result code translation error on big-endian systems
- fix resource releasing bug when scsi_host_alloc() fail in hptiop_probe()
- update scsi_cmnd.resid when finishing a request
- correct some coding style issues

The driver registers char device "hptiop" to communicate with HighPoint RAID

management software. Its ioctl routine acts as a general binary interface 

between the IOP firmware and HighPoint RAID management software. New management

functions can be implemented in application/firmware without modification

in driver code.
