Fixes for omaps, all dts changes except for one:
- Fix up LCD panel name for overo boards
- Three fixes for pepper board for regulators, freqeuncy
scaling and audio input. Note that there is still one
issue being worked on for booting with multi_v7_defconfig
- Add missing #iommu-cells for omap4 and 5
- Add missing HAVE_ARM_SCU for am43xx
