cpu/x86: Add some notes about XAPIC/X2APIC
At the time of writing SMM runtime does not make register
accesses to LAPIC registers, but such breakage has been
reported.
S3 resume failure, where OS switched back from X2APIC
to XAPIC mode, can be reproduced with a sandybridge SKU
that has VT-d disabled.
