reset: Add reset controller API This adds a simple API for devices to request being reset by separate reset controller hardware and implements the reset signal device tree binding.

reset: Add of_reset_control_get to reset.h of_reset_control_get is not declared static in drivers/reset/core.c, which is correct as we want to use it elsewhere too. But it does not have a protype declared anywhere under include/linux. Add a prototype / stub for it to linux/reset.h to fix this.

reset: Add optional resets and stubs This patch adds device_reset_optional and (devm_)reset_control_get_optional variants that drivers can use to indicate they can function without control over the reset line. For those functions, stubs are added so the drivers can be compiled with CONFIG_RESET_CONTROLLER disabled. Also, device_reset is annotated with __must_check. Drivers ignoring the return value should use device_reset_optional instead.

reset: add reset_control_status helper function There are cases where a system will want to read a reset status bit before doing any other toggling.
