ppc/pnv: Move PNOR to offset 0 in the ISA FW space

skiboot has a bug that does not handle ISA FW access correctly for IDSEL
devices > 0, and the current PNOR default address and size puts 64MB in
device 0 and 64MB in device 1, which causes skiboot to hit this bug and
breaks PNOR accesses.

Move the PNOR address down to 0 for now, so a 256MB PNOR can be accessed
via device 0.
