[PATCH v3 2/4] arm64: dts: google: Add dts directory for Google-designed silicon

[Peter Griffin]

From: Douglas Anderson <dianders@xxxxxxxxxxxx>

The first four Google Tensor SoCs were offshoots of Samsung Exynos
SoCs and their device trees were organized under the "exynos/google"
directory. Starting with the Google Tensor G5 SoC in Pixel 10 phones,
Google Tensor SoCs are now of Google's own design. Add a location in
the tree to store these device tree files.

 * update config symbol help with at least 4 lines to avoid checkpatch
