At the moment we have 2 seperate device tree sources: 1 for ipq8064 soc located
in kernel source and 1 custom in LEDE for ipq8065.
ipq8064 and ipq8065 SoCs are completely identical except ipq8065 has higher cpu
frequencies and adjusted corresponding power supply.
This commit makes ipq8065 DTS to contain only specific for ipq8065 DT entries while
pulling all the basic SoC stuff from ipq8064 DTS.
It makes easier to manage ipq806x device trees and instead of committing changes into

It is not possible to flash LEDE via the TP-Link webinterface. The

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.

DB149 is a IPQ8064 based platform. This patch adds the init scripts to
detect it, configure the network accordingly, and generate a flashable
image for it.
