[RFC] setup.c: get ride of CPHYSADDR()

[Franck Bui-Huu <vagabon.xyz@gmail.com>]

Hi,

The following patch is an attempt to remove this macro in setup.c.
I'm not sure about why sometimes it is used and sometimes it is
not. By sending this RFC, I hope to get some feedbacks that will shed
some light on this obscure macro...

The reason why I'm trying to kick out this macro is that we should
rely on __pa() for address convertions instead of having several
helpers that do the same thing but differently. Futermore if some
tricks are needed for these conversions, they should be done in
one place.

Thanks
		Franck
