x86, olpc: Rework BIOS signature check
The XO-1.5 laptop is not currently detected as an OLPC machine because
it fails this XO-1-centric check.
Now that we have OLPC OFW support in the kernel, a more sensible
check is to see if we found OFW during boot and check the architecture
property.
Also remove a now-meaningless codepath, as we're always going to have
OFW support with OLPC.
