Right, each of the three CMOS/RTC devices in the ACPI spec has a
different ACPI ID (PNP0B00, PNP0B01, PNP0B02).  FreeBSD's CMOS RTC
driver only attaches to PNP0B00; if a different CMOS device is present,
there will be no CMOS/RTC driver (since we don't know how to talk to
it).  Should be a no-op, like for any unsupported device.

If I had the specs for each of those devices, I could probably cobble
together support for the other two, but that wasn't my original mission...
