x86/microcode: Issue update message only once
This is especially annoying on large boxes:
x86: Booting SMP configuration:
.... node #0, CPUs: #1
microcode: CPU1 microcode updated early to revision 0x428, date = 2014-05-29
#2
microcode: CPU2 microcode updated early to revision 0x428, date = 2014-05-29
#3
...
so issue the update message only once.
$ grep microcode /proc/cpuinfo
shows whether every core got updated properly.
