Merge tag 'imx-dt-3.8' of git://git.linaro.org/people/shawnguo/linux-2.6 into next/dt

From Shawn Guo <shawn.guo@linaro.org>:
It's based on imx/multiplatform branch.  Most of them are dts changes.
There are also a few imx6 improvement patches in there.

* tag 'imx-dt-3.8' of git://git.linaro.org/people/shawnguo/linux-2.6:
  ARM: imx6q: select ARM and PL310 errata
  ARM: imx6q: print silicon version on boot
  ARM i.MX dts: Consistently add labels to devicenodes
  ARM: dts: imx6q-sabresd: add volume up/down gpio keys
  ARM: dts: imx53: pinctl update
  ARM: imx: enable cpufreq for imx6q
  ARM: dts: imx6q: enable snvs lp rtc
  ARM: dts: imx6q-sabreauto: Add basic support
  ARM: imx6q: let users input debug uart port number
  ARM: dts: imx53-qsb: Make DA9053 regulator functional
  ARM: dts: imx53-qsb: Use pinctrl for gpio-led
  ARM i.MX dtsi: Add default bus-width property for esdhc controller
