attached my patch for the aha152x driver.  Tested for pcmcia and not
pcmcia and various devices.

changes in the aha152x driver:
- gather code that is not used by PCMCIA at the end
- move request_region for !PCMCIA case to detection
- migration to new scsi host api (remove legacy code)
- free host scribble before scsi_done
- fix error handling
- one isapnp device added to id_table

and in the pcmcia stub module:
- default to synchronous transfers
- release_region hack removed
- let core module do the scsi host api calls.
