[PATCH] x86: Pnp segments in segment h
Move PnP BIOS segment definitions into segment.h; the segments are reserved
here, so they might as well be defined here as well.
Note I didn't do this for APM BIOS, as Macintosh and other systems use those
values to emulate APM in some scary way I don't want to understand.
