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 v3
* Addressed Stefen's review comments on patch 14/16
* Fixed kernel test robot warning on patch 04/16
* rebsaed this series on Krzysztof's pinmux new binding schema work [1]

- Changes since v2
* Addressed Krzysztof's and Stephen's review comments
* Added Reviewed-by and Acked-by tags
* Rebased on next-20220120

- 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
* Dropped SPI, MCT and ADC from this series (to be posted in small sets)

NOTE: These patches are based on Krzysztof's pinmux for-next branch
