Subject: [PATCH v2 0/2] Add support for Pixel 3 and Pixel 3 XL

This adds initial device tree support for the following phones:

 - Google Pixel 3 (blueline)
 - Google Pixel 3 XL (crosshatch)

Both phone boards use the same identifiers and differ only slightly
in their connected peripherals.

This is mainly focused to get the base functionality of the board and
being able to use the upstream DTS within Linux and u-boot.

Booting
-------
For older Pixel 3 bootloaders, bootloader-compatible board and MSM IDs are
required for the kernel to boot, so these have been added.

For recent Pixel 3 bootloaders,
a) you want chainloaded proper bootloader (f.e. u-boot),
b) you can also boot kernel when adding back TEXT_OFFSET
   (partial revert of 120dc60d).

This series is a beggining of cleaning up and transitioning support from
sdm845 close to mainline tree to the mainline.

Note: I assume this won't get merged yet, but all or at least most of
initial feedback to v1 should be incorporated.

Depends on:
- "[PATCH 0/7] arm64: dts: qcom: cleanup GPU's zap-shader node" series.
