x86, setup: Phoenix BIOS fixup is needed on Dell Inspiron Mini 1012

The low-memory corruption checker triggers during suspend/resume, so we
need to reserve the low 64k. Don't be fooled that the BIOS identifies
itself as "Dell Inc.", it's still Phoenix BIOS.

[ hpa: I think we blacklist almost every BIOS in existence. We should
either change this to a whitelist or just make it unconditional. ]
