This setting does not need to be conditional on Atari ST or TT.

Changed since v1:
- Set the default cmd_per_lun to 4 based on test results.
Changed since v2:
- Revert the default cmd_per_lun to 2, like in the v1 patch, because
a uniform default across all ten 5380 wrapper drivers is worth more
than a tiny improvement in one particular microbenchmark on one system.
Michael tells me that 2 is also the best setting for his Atari Falcon.
