[PATCH] voyager: fix compile after setup rework

The following

[PATCH] Clean up and refactor i386 sub-architecture setup

Doesn't quite work, since it leaves out an include of asm/io.h, without
which the use of inb/outb in the setup file won.t work.  This corrects that
and also removes a spurious acpi reference that apparently crept in ages
ago but should never have been there.
