This change adds PCIe support to IPQ806x based platforms. The driver is
actually cherry-picked from the following LKML thread:
*https://lwn.net/Articles/643086/ (patches 110-111)
We also add here an additional fix to support multiple PCI controllers
on the same platform (patch 112), and to patch the ap148 & dbs149 DTS
files (patch 113).

This change enable zImage+appended dtb support in ipq806x kernel
options. The zImage will now be generated as part of the kernel
binaries. Platforms which do not have DT support enabled in U-boot
can now make use of it by generating zImage files and appending dtb
to it.
It is not used yet but it is done as a stepping stone for early IPQ806x
platforms, which did not include DT support in U-boot.

ARCH_QCOM is using the ARCH_MULTIPLATFORM option, as now recommended
on most ARM architectures. This automatically calculate ZRELADDR by
masking PHYS_OFFSET with 0xf8000000.
On IPQ806x though, the first ~20MB of RAM is reserved for the hardware.
In newer bootloader, when DT is used, this is not a problem, we just
reserve this memory in the device tree. But if the bootloader doesn't
have DT support, then ATAGS have to be used. In this case, the ARM
decompressor will position the kernel in this low mem, which will not be
in the RAM section mapped by the bootloader, which means the kernel will
freeze in the middle of the boot process trying to map the memory.
As a work around, this patch allows disabling AUTO_ZRELADDR when
ARCH_QCOM is selected. It makes the zImage usage possible on bootloaders
which don't support device-tree, which is the case on certain early
IPQ806x based designs.

This patch allows AP148 to boot from NOR flash.
As we're using a FIT image as kernel (which includes kernel bin + DTB)
we enable the MTD_SPLIT_FIT_FW kernel option, which will detect the FIT
image and automatically split the "firmware" partition into 2 MTD parts
(kernel + rootfs).
The rootfs will then be parsed and split between rootfs + rootfs_data,
as usual.

The watchdog driver already registers a restart notifier, we just have
to enable it in the config and in the DT to fix the "reboot" command.
This is done by integratin the following patch-set:
https://lkml.org/lkml/2015/2/20/610
I'm copy-pasting the description below:
qcom-wdt is currently assuming the presence of a dedicated node in DT
to gets its configuration. However, on msm architecture, the watchdog is
usually part of the timer block. So this patch-set is changing the driver
and slightly enhancing the timer DT bindings to provide the relevant clocks
and interrupts.

Some bootloaders seem to trigger the watchdog during the boot process,
therefore the lack of watchdog driver trigger a reboot a few seconds
after boot. So we'll enable it here to avoid it.

Patches in the ipq806x/patches folder were out of tree in v3.14. The
newest patch at the time was from June, so we can safely assume that
either the patches have been merged, or they have been rejected for
a good reason. If patches are seen missing, we'll cherry-pick them
on a per-needed basis.
This new kernel have been tested on AP148, which seems to works fine.

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.
