(The diff of the patch is identical to the diff of a quick hacked
patch I made weeks ago for my BSP which fixed the issue.  SoC variant
was reported correctly on serial console on boot again.  However I did
not actually test *your* patch on my hardware (sam9x60 curiosity),
thus Acked-by and not Tested-by.)
