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 059/182] spmi: pm: drop bus-level PM suspend/resume routines
+
+SPMI defines the behavior of a device in the "SLEEP" state as being
+"user-defined or specified by the device manufacturer".  Without
+clearly-defined bus-level semantics for low-power states, push the
+responsibility of transitioning a device into/out of "SLEEP" into SPMI
+device drivers.
