Print this only once, for the boot CPU, unless "cpuinfo" was
specified.
I found this particularly annoying on a machine which also didn''t have
it MTRRs consistently set up across cores, resulting in the printing of
those messages being awfully slow (and with a second per-CPU message
added for debugging purposes this even lead to timeouts during AP
bringup).
