x86/cpu: Switch to arch_cpu_finalize_init()

Browse Source 
commit 7c7077a72674402654f3291354720cd73cdf649e upstream

check_bugs() is a dumping ground for finalizing the CPU bringup. Only parts of
it has to do with actual CPU bugs.

Split it apart into arch_cpu_finalize_init() and cpu_select_mitigations().

Fixup the bogus 32bit comments while at it.

No functional change.
