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 104/182] clk: qcom: Return highest rate when round_rate()
+ exceeds plan
+
+Some drivers may want to call clk_set_rate() with a very large
+number to force the clock to go as fast as it possibly can
+without having to know the range between the highest rate and
+second highest rate. Add support for this by defaulting to the
+highest rate in the frequency table if we can't find a frequency
+greater than what is requested.
