Provide both __OFFSET and __PADDR for SCR entries

Browse Source 
This was recently changed to write out physical addresses for SCR file entries,
but to bring up the chip we need SCR offsets so we can write the uncore SCR
file over HTIF.  This changes the map generator to generate both.

Without this change things happened to work anyway because the high bits were
getting dropped by the SCR file.
