Merge tag 'imx-cleanup-3.10' into imx/soc

The imx cleanup for 3.10:

* Clean up a couple of unneeded function declarations
* Remove imx specific cpufreq driver as generic cpufreq-cpu0 works well
  as the replacement
* Remove platform ahci support
* Clean up unused ARCH/MACH Kconfig symbols
* Remove a couple of unused files
