[PATCH 1/4] arm: Add Google Tensor SoC architecture support

[Kuan-Wei Chiu <visitorckw@gmail.com>]

The first four Google Tensor SoCs were offshoots of Samsung Exynos
SoCs. Starting with the Google Tensor G5 SoC in Pixel 10 phones,
Google Tensor SoCs are of Google's own design. Add ARCH_GOOGLE and
the mach-google directory to support this SoC family.
