[PATCH 2/4] arm64: dts: qcom: add sdm845-google-blueline (Pixel 3)

From: Amit Pundir <amit.pundir at linaro.org>
This adds an initial dts for the Blueline (Pixel 3). Supported
functionality includes display, Debug UART, UFS, USB-C (peripheral), WiFi,
Bluetooth and modem.
Bootloader compatible board and msm IDs are needed for the kernel to boot
with Pixel3 bootloader, so those are added.
GPIOs 0 through 3 and 81 through 84 are configured to not be accessible
from the application CPUs, so we mark them as reserved to allow the Pixel 3
to boot.
The reserved-memory locations where obtained from downstream using
kernel logs:
https://gist.github.com/calebccff/090d10bfac3cb9e9bd98dda30b054c96
The rmtfs region is allocated with UIO, making it technically "dynamic".
It's address and size can be read from sysfs:
blueline:/ # cat /sys/class/uio/uio0/name
rmtfs
at /sys/class/uio/uio0/maps/map0/addr
0x00000000f2701000
blueline:/ # cat /sys/class/uio/uio0/maps/map0/size
0x0000000000200000
Like the OnePlus 6, it needs 1kB reserved on either side of the rmtfs
memory to workaround some XPU bug which would otherwise cause erroneous
XPU violations when accessing the rmtfs_mem region.
For wifi, the pixel 3 reports a board-id of 0xFF, and downstream
only includes a single bdwlan file. The qcom,ath10k-calibration-variant
property is set to ensure that the correct calibration data is used.
