> 
> Add basic Power Management Unit (PMU) driver for Exynos SoCs. For now
> it's only capable of changing UART path in PMU, which is needed for
> E850-96 board. The driver's structure resembles the exynos-pmu driver
> from Linux kernel, and although it's very basic and slim at the moment,
> it can be easily extended in future if the need arises.
> 
> UCLASS_NOP is used, as there are no benefits in using more elaborate
> classes like UCLASS_MISC in this case. The DM_FLAG_PROBE_AFTER_BIND flag
> is added in bind function, as the probe function must be always called
> for this driver.
