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 162/182] PM / OPP: Remove ARCH_HAS_OPP
+
+Since the OPP layer is a kernel library which has been converted to be
+directly selectable by its callers rather than user selectable and
+requiring architectures to enable it explicitly the ARCH_HAS_OPP symbol
+has become redundant and can be removed. Do so.
