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 120/182] ahci_platform: Drop support for imx53-ahci platform
+ device type
+
+Since the 3.13 release the ahci_imx driver has proper devicetree enabled
+support for ahci on imx53 and that is used instead of the old board file
+created imx53-ahci platform device.
+
+Note this patch also complete drops the id-table, an id-table is not needed
+for a single id platform driver, the name field in the driver struct suffices.
+
+And the code already has an explicit "MODULE_ALIAS("platform:ahci");" so the
+id-table is not needed for that either.
