Adds basic support for the Tesla Full Self-Driving (FSD)
SoC. This SoC contains three clusters of four Cortex-A72 CPUs,
as well as several IPs.

Patches 1 to 9 provide support for the clock controller
(which is designed similarly to Exynos SoCs).

The remaining changes provide pinmux support, initial device tree support.

- Changes since v1
* fixed make dt_binding_check error as pointed by Rob
* Addressed Krzysztof's and Rob's review comments
* Added Reviewed-by and Acked-by tags
* Reordered the patches
* Dropped SPI, MCT and ADC from this series (to be posted in small sets)

NOTE: These patches are based on next-20220118

Alim Akhtar (16):
