2.5.4-pre6 pci/proc.c compile fix

Hi Linus,

The attached patch fixes the following compile warning in 2.5.4-pre6:

proc.c: In function `proc_bus_pci_read':
proc.c:49: warning: passing arg 1 of PDE' discards qualifiers from pointer target type proc.c: In function proc_bus_pci_write':
proc.c:131: warning: passing arg 1 of `PDE' discards qualifiers from pointer target type

I see no reason why the two inline functions should not use const qualifier. Otherwise the caller in proc.c should be fixed.

Regards,
Udo.
