x86/cpu: Constify struct x86_cpu_id
'struct x86_cpu_id' is not modified in this compilation unit.
Constifying this structure moves some data to a read-only section, so
increases overall security.
It is only used in cpu_has_old_microcode() which is an __init function. So,
using __initconst is safe and will save about 6 kB of memory at runtime.
On a x86_64, with allmodconfig:
