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

Signed-off-by: Kumar Gala <galak@codeaurora.org>

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
