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 097/182] ARM: debug: qcom: make UART address selection
+ configuration option
+
+Separate Qualcomm low-level debugging UART to two options.
+
+DEBUG_MSM_UART is used in earlier non-multi platform arches,
+like MSM7X00A, QSD8X50 and MSM7X30.
+
+DEBUG_QCOM_UARTDM is used in multi-plafrom arches and have
+embedded data mover.
+
+Make DEBUG_UART_PHYS and DEBUG_UART_BASE user adjustable by
+Kconfig menu.
