Adrian Schmutzler b7b7c2a6ad ipq806x: use qcom-ipq8064.dtsi from upstream
Though a qcom-ipq8064.dtsi file exists upstream, we still do overwrite
it with a full version of our own in the ipq806x target. About half of
the contents of our file are upstream content, the other half are local
improvements.

To prevent us from having a lot of code maintained twice in parallel,
this adjusts the target to use the upstream qcom-ipq8064.dtsi. Our
local changes are arranged into three patches, the first pulling a
commit from upstream, the second doing a few small adjustments, and
the third adding all additional stuff.

This should get us the best of both worlds.

The property "ports-implemented" on sata@29000000 is moved to
2nd-level DTSI files as kernel defines it there as well.

While at, rename 080-ARM-dts-qcom-add-gpio-ranges-property.patch to
include the kernel version where it's added upstream.

Even though this might look more complicated in the first place,
the aim is to bring our files closer to upstream, so we can benefit
from changes directly and vice-versa. After all, this drop about
650 lines just copied from the upstream DTSI file.

This patch adds the gpio-ranges property to almost all of
the Qualcomm ARM platforms that utilize the pinctrl-msm
framework.
The gpio-ranges property is part of the gpiolib subsystem.
As a result, the binding text is available in section
"2.1 gpio- and pin-controller interaction" of
Documentation/devicetree/bindings/gpio/gpio.txt
For more information please see the patch titled:
"pinctrl: msm: fix gpio-hog related boot issues" from
this series.

To help with git bisect, the DT update patch has been intentionally
placed after the "pinctrl: msm: fix gpio-hog related boot issues".
Otherwise - if the order was reveresed - and bisect decides to split
between these two patches, the gpiochip_add_pin_ranges() function
will be executed twice with the same parameters for the same pinctrl.
