[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.
