intelli_plug driver from @faux123
intelli_plug: move to its own directory. It's been cross platform for a while

intelli_plug driver has been working on OMAP44xx, TEGRA 3, Exynos and
MSM Krait/Cortex multi-core SOCs.  So it doesn't make sense to patch on a per
SOC basis, move it to its own ARM platform independent folder so patches can
apply to all supported ARM platforms
