	  Enable support for the reset controller driver class. Many hardware
	  modules are equipped with a reset signal, typically driven by some
	  reset controller hardware module within the chip. In U-Boot, reset
	  controller drivers allow control over these reset signals. In some
	  cases this API is applicable to chips outside the CPU as well,
	  although driving such reset isgnals using GPIOs may be more
	  appropriate in this case.

Add a reset driver framework/uclass A reset controller is a hardware module that controls reset signals that affect other hardware modules or chips. This patch defines a standard API that connects reset clients (i.e. the drivers for devices affected by reset signals) to drivers for reset controllers/providers. Initially, DT is the only supported method for connecting the two. The DT binding specification (reset.txt) was taken from Linux kernel v4.5's Documentation/devicetree/bindings/reset/reset.txt.
