Some SoCs (for example Amlogic GXBB) implement a reset controller which only supports a reset pulse (triggered via reset_control_reset). At the same time multiple devices (in case of the Amlogic GXBB SoC both USB PHYs) are sharing the same reset line. This patch allows using reset_control_reset also for shared resets. There are limitations though: reset_control_reset can only be used if reset_control_assert was not used yet. reset_control_assert can only be used if reset_control_reset was not used yet. For shared resets the reset is only triggered once for the lifetime of the reset_control instance (the reset can be triggered again if all consumers of that specific reset_control are gone, as the reset framework will free the reset_control instance in that case).
