[9front] [patch] 9/port/sdaoe: remove unfinished atapi support

[Arne Meyer <meyer.arne83@netcologne.de>]

sdaoe has some vestigial code that was probably meant to support atapi. this depends on code from sdscsi,
which is not reflected in the conf files for pc and pc64 but sdscsi gets pulled in by other drivers and compiles by accident.
