[PATCH] powerpc: Update OF address parsers

Browse Source 
This updates the OF address parsers to return the IO flags
indicating the type of address obtained. It also adds a PCI
call for converting physical addresses that hit IO space into
into IO tokens, and add routines that return the translated
addresses into struct resource
