PMU interrupt generation block is not present in older Samsung Exynos
SoCs, so restrict the property to Google GS101 only.

gs101 requires access to the pmu interrupt generation register region
which is exposed as a syscon. Update the exynos-pmu bindings documentation
to reflect this.

Document the compatible string for the Exynos7870 PMU. It's compatible
with the Exynos7 PMU design. It handles syscon reboot, syscon reboot mode,
as well as other system control registers (i.e registers for the USB PHY).

Add exynos2200-pmu compatible to the bindings documentation. Since
Samsung, as usual, reuses devices from older designs, use the
samsung,exynos7-pmu compatible.

Add compatible for Samsung Exynos9810 PMU to the schema.
Like on other devices, it contains various registers related
to power management and other vital to SoC functions.

Tesla FSD is a derivative of Samsung Exynos SoC, thus just like the
others it reuses several devices from older designs. Historically we
kept the old (block's) compatible only. This works fine and there is no
bug here, however guidelines expressed in
Documentation/devicetree/bindings/writing-bindings.rst state that:
1. Compatibles should be specific.
2. We should add new compatibles in case of bugs or features.
Add Tesla FSD compatible specific to be used with an existing fallback.

Support for the Exynos4212 SoC was originally dropped as there were
no boards using it. We will be adding a device that uses it, so add
back the relevant compatible.
This reverts part of commit c40610198f ("soc: samsung: Remove
Exynos4212 related dead code").

Recently added Samsung Exynos USI driver devicetree bindings were added
under ../bindings/soc/samsung/exynos-usi.yaml, so move there also two
other bindings for Exynos SoC drivers: the PMU and ChipID.
Update Samsung Exynos MAINTAINERS entry to include this new path.
