scsi/NCR5380: fix and standardize NDEBUG macros
All three NCR5380 core driver implementations share the same NCR5380.h header file so they need to agree on certain macro definitions. The flag bit used by the NDEBUG_MERGING macro in atari_NCR5380 and sun3_NCR5380 collides with the bit used by NDEBUG_LISTS. Moreover, NDEBUG_ABORT appears in NCR5380.c so it should be defined in NCR5380.h rather than in each of the many drivers using that core. An undefined NDEBUG_ABORT macro caused compiler errors and led to dodgy workarounds in the core driver that can now be removed. (See commits f566a576bca09de85bf477fc0ab2c8c96405b77b and 185a7a1cd79b9891e3c17abdb103ba1c98d6ca7a.) Move all of the NDEBUG_ABORT, NDEBUG_TAGS and NDEBUG_MERGING macro definitions into NCR5380.h where all the other NDEBUG macros live. Also, incorrect "#ifdef NDEBUG" becomes "#if NDEBUG" to fix the warning: drivers/scsi/mac_scsi.c: At top level: drivers/scsi/NCR5380.c:418: warning: 'NCR5380_print' defined but not used drivers/scsi/NCR5380.c:459: warning: 'NCR5380_print_phase' defined but not used The debugging code is now enabled when NDEBUG != 0.
