Subject: [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
