Subject: [PATCH v2 3/3] arm64: dts: exynos: gs101-raven: add new board file

Raven is Google's code name for Pixel 6 Pro. Similar to Pixel 6
(Oriole), this is also based around its Tensor gs101 SoC.

For now, the relevant difference here is the display resolution:
1440 x 3120 instead of 1080 x 2400.

Create a new board file to reflect this difference.
