PNP cleanups

Hi,

I wonder whether these rather large cleanups can already be added to some mainline branch.

There should be no functional change.

This could make life easier for me (not that bad, there were not that much changes in the past), but mainly make it easier for others to test the real patch, that should reduce memory waste in pnp layer and I expect some testing (especially on older isa machines) will be necessary...

The intend is to unify the pnp_{port,mem,dma,irq}_... macros exposed in include/linux/pnp.h and make use of them more consequently.

The patches apply on 2.6.24-rc2-mm1

Thanks,

Thomas

I can volunteer some ISA-PnP testing.

Patches against the current -stable are generally easiest for me as my ISA test machines are slow enough to not enjoy frantically keeping up with the absolute latest and greatest on them -- but I guess I'll manage.
