Thanks Stephen,

Sorry I've been MIA, things have been a little crazy here.

If I move the pwm label, should I move the others as well?  Do we want
to use the same method that has been used for exynos5250?  Exynos has
a label on most things that are overridden and the .dts files that
override them, like exynos5250-snow.dts, access them with &label
syntax.  It's easy for me to do, but it will involve converting
venice2 and jetson as well to avoid label re-defines.
