The addr_unlock values set in cfi_probe_chip() are supposed to compensate
for that. We can't do it by shifting by the device_type, because sometimes 
we need to put an odd address value on the bus for 16-bit chips. 

But the actual _detection_ of CFI chips shouldn't be affected by that 
anyway, unless it's falling back to the JEDEC probe.
