Add a new reset_name field to the spacemit_ccu_data structure. If it is non-null, the CCU implements a reset controller, and the name will be used in the name for the auxiliary device that implements it. Define a new type to hold an auxiliary device as well as the regmap pointer that will be needed by CCU reset controllers. Set up code to initialize and add an auxiliary device for any CCU that implements reset functionality. Make it optional for a CCU to implement a clock controller. This doesn't apply to any of the existing CCUs but will for some new ones that will be added soon.
