x86: Add NumaChip support
Adds support for Numascale NumaChip large-SMP systems. It is
needed to enable the booting of more than ~168 cores.
v2:
- [Steffen] enumerate only accessible northbridges
- [Daniel] rediffed and validated against 3.1-rc10
v3:
- [Daniel] use x86_init core numbering override
- [Daniel] cleanups as per feedback
v4:
- [Daniel] use updated x86_cpuinit override
v5:
- drop disabling interrupts locally, as ISR write is atomic; drop delay
- added read-mostly annotations where appropriate
- require CONFIG_SMP, so drop conditional path
Workload tested on 96 cores/16 sockets.
