Implement a clock uclass driver for the Tegra CAR. This allows clients to use standard clock APIs on Tegra. This device is intended to be instantiated by the core Tegra CAR driver, rather than being instantiated directly from DT. The implementation uses the existing custom Tegra- specific clock APIs to avoid coupling the series with significant refactoring of the existing Tegra clock/clock code. The driver currently only supports peripheral clocks, and avoids support for other clocks such as PLLs and external clocks. This should be sufficient to convert over all Tegra peripheral drivers, and avoids a complex implementation which calls different Tegra-specific clock APIs based on the type of clock being manipulated.
