[PATCH] Atari NCR5380 SCSI: bitops operate on long
Atari NCR5380 SCSI driver tag bitmap updates:
- Use DECLARE_BITMAP() to declare the tag bitmap
- Remove `MAX_TAGS must be a multiple of 32', which is no longer true
- Declare and use CLEAR_BITMAP() to set all bits in a bitmap to zero
- Fix bitops call problems that got unnoticed before
