[RFC PATCH 2/2] configs: Add google-pixel3 fragment config for Pixel 3 / 3 XL

[David Heidelberg]

Introduce a fragment config for the Pixel 3 and Pixel 3 XL.

On these devices, U-Boot must be chainloaded via Fastboot. However, due to
a Fastboot bug, U-Boot won’t start unless a specific condition is met.

To work around this, U-Boot must provide a TEXT_OFFSET of 0x00080000,
which allows Fastboot to successfully launch U-Boot.

Instead of:
$ make CROSS_COMPILE=aarch64-linux-gnu- O=.output qcom_defconfig qcom-phone.config
do
$ make CROSS_COMPILE=aarch64-linux-gnu- O=.output qcom_defconfig google-pixel3.config qcom-phone.config
