/proc/pci is still obsolete in 2.2.x

Hello.

After an user of us (debian) complained about the "xxx uses obsolete /proc/pci interface",
I noticed that in 2.2.19, drivers/pci/oldproc.c, line 1042

Now 2.3/2.4 this interface is still available and no more considered as obsolete, thus this warning should be removed (and maybe also the file should be remerged to the proc.c as in 2.4).
