This patch adds rpm node to apq8064 dt as rpm would be used by other
devices for regulator support. Also adds all the regulators in the rpm.

Some comments on the compatibles, based on rpm-regulator-8960 msm-3.4.

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).

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.

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.

I agree with you.

Yes.. I had the same feeling when I started adding this.. But I wanted 
to send it for review and see.
