Previous patch 6f2905eeb6ce5ddec8d12d677e1f377a940b537b enabled ADM in
the kernel, which causes a kernel panic when accessing the SPI flash.
As a workaround, We'll disable DMA for the flash for now. It was not
enabled previously anyway so we'll just leave it as is.

Previous patch set backported the recently posted NAND flash driver to
3.18 and 4.1 kernel. This patch now enables it in the kernel config.
There is no change to the partition layout and init yet. But the NAND
flash can be seen in the mtd list on an AP148:
root@OpenWrt:/# cat /proc/mtd
dev: size erasesize name
mtd0: 10000000 00020000 "qcom-nandc"

They are enabled on both 3.18 and 4.1 kernel. Patches 150 to 154 are
applying changes merged since 3.18; they enable mechanisms used by the
ADM driver.
ADM engine is used by the NAND controller, so it is necessary to
bring-up NAND flash support.

Old bootloader (same ones which have DT disabled) don't perform any PCIe
initialization. The consequence is a freeze during PCIe bring-up on
these old u-boot. Same kernel with a newer bootloaders works fine as
they contain the corresponding PCIe init code.
In this change, we'll add the missing init and make sure the kernel
doesn't rely on some preexisting init to get PCIe to work. That includes
the following changes:
*GPIOs: set function & drive strength
*Clocks: add init code for aux & ref clocks
*PCIe driver: additional init of the hardware controller
Tested 3.18 and 4.1 on an AP148 with bootloader branch 0.0.1

Certain AP148 platforms (and derivative) use bootloaders which did not
have DT enabled.
In order to support these old platforms, we'll now make the following
modifications:
*explicitely add the memory node in the AP148 DT: this used to be added
by new u-boot through a run-time patch mechanism. We'll now add it
explicitely so it works on boots which don't support that feature. New
boots will have the node twice, the second one will be ignored.
*add the zImage generation next to the FIT image for AP148.
Other platforms using non-DT enabled bootloaders may want to leverage
this zImage code to generate their own firmare as well.

Disable the i2c device on gsbi4 and mark gsbi4_h and gsbi4_qup clks as
unused. If they are enabled, clock framework will turn them off at end

are meant for RPM usage. So turning them off in kernel is incorrect.

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.
