[RFC PATCH 0/8] ARM: qcom: msm8960: support CPU frequency scaling

This is an RFC (or maybe it should be RFT), as I did not test this on
the actual hardware. The actual core and L2 setup is mostly the same as
APQ8064, so this is just a port of APQ8064 code and adaptation for small
MSM8960 peculiarities.

Note, msm-3.4 had separate optional AVS code for MSM8960, but as I don't
have the actual hardware, it is left untouched for now.

Dependencies: [1].
