Merge "The i.MX fixes for 4.1, 3rd round" from Shawn Guo:

It includes a couple of fixes for i.MX6 GPC code to let the new kernel
be able to boot with old DTBs:

 - Booting v4.1-rc kernel with old DTBs will fail with a fat warning
   (require low-level debug to be seen), due to the adoption of stacked
   IRQ domain.  The first fix improves the situation by allowing kernel
   boot up with old DTBs, although suspend/resume still breaks.

 - Booting new kernel with old DTBs that do not have power-domain info
   will result in a hang.  The second patch fixes the hang by skipping
   the kernel power-domain registration if DTB has no power-domain info.
