[PATCH v2] ARM: qcom: Add initial IPQ8064 SoC and AP148 device trees

[Kumar Gala <galak-sgV2jX0FEOL9JmXXK+q4OQ@public.gmane.org>]

Add basic IPQ8064 SoC include device tree and support for basic booting on
the AP148 Reference board.  Also, keep dtb build list and qcom_dt_match in
sorted order.

v2:
* created a v1.0 ipq8064.dtsi to handle differences in Si rev in future
* changed /include/ to #include
* fixed timer freq to be 25Mhz instead of 27Mhz (copied from msm8960)
* added PMU node
* dropped interrupts from cpus node, not currently part of binding
