at such case We need to enable 8 bit ext apic id mode for Opteron. So Opteron could use 0x10 above.
and leave 0-0x0f to the device that can not support 8 bit apic id.
I'm considering to align apic id lifting to the way that Norma BIOS does.

With the set of changes apicids will be 0x0-0x0f with 8way dual cores.
If that is not sensible we can change the generic code as all of
the apicid assignment is now in generic code.
