Right now we run through the errata workarounds check on all boot active CPUs, with SCOPE_ALL. This doesn't help with detecting the errata's with a SYSTEM_SCOPE. While nobody uses it, let us clean this up in preparation for merging capability handling.
So, we run the checks with SCOPE_LOCAL_CPU on all CPUs and SCOPE_SYSTEM checks are run only once after all the boot time CPUs are active.
