This patch adds rpm node to apq8064 dt as rpm would be used by other

Some comments on the compatibles, based on rpm-regulator-8960 msm-3.4.
Thanks for the review. I kind of grabbed a table from datasheet,
obviously my interpretation of some of them are wrong. I should have
looked at rpm-regulator-8960.c.
I will fix them in next version.
After giving this some more thought I think it would be good to defer the
voltage definition to the dts files, at least for the ldos (as these are being
re-purposed).
I agree with you.
That way the dts implementor will be the one frying their components and not us
because some default value kicking in because someone miss-spelled or forgot to
override a certain voltage.
Yes.. I had the same feeling when I started adding this.. But I wanted
to send it for review and see.
