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.
