x86: cpu: make sure number of addressable IDs for processor cores meets the spec
Accourding Intel's CPUID[EAX=04H] resulting bits 31 - 26 in EAX
should be:
"
**** The nearest power-of-2 integer that is not smaller than (1 + EAX[31:26]) is the number of unique
Core_IDs reserved for addressing different processor cores in a physical package. Core ID is a subset of
bits of the initial APIC ID.
"
ensure that values stored in EAX[31-26] always meets this condition.
