ipq806x: Add support for IPQ806x chip family

Patches are generated using the "format-patch" command from the
following location:
*https://www.codeaurora.org/cgit/quic/kernel/galak-msm/log/?h=apq_ipq_base
*rev=0771849495b4128cac2faf7d49c85c729fc48b20
Patches numbered 76/77/102/103 have already been integrated in 3.14.12,
so they're not in this list.

All these patches are either integrated are pending integration into
kernel.org, therefore these patches should go away once the kernel
gets upgraded to 3.16.

Support is currently limited to AP148 board but can be extended to other
platforms in the future.

These changes do not cover ethernet connectivity.

+Subject: [PATCH 092/182] ARM: dts: qcom: Update msm8960 device trees
+
+* Move SoC peripherals into an SoC container node
+* Move serial enabling into board file (qcom-msm8960-cdp.dts)
+* Cleanup cpu node to match binding spec, enable-method and compatible
+  should be per cpu, not part of the container
+* Drop interrupts property from l2-cache node as its not part of the
+  binding spec
+* Add GSBI node and configuration of GSBI controller
