core: detect LPAR-per-core mode and report in dt
Some firmware configurations boot in LPAR-per-core mode, which is not
compatible with KVM on POWER9 and later machines.
Detect which LPAR mode the boot core is in (all others will be set
the same way), and if booted in LPAR-per-core mode then print a warning
and add a device-tree entry that the OS can test for.
