Some SoCs from Aspeed, Allwinner, Sophgo and Synopsys have a simple reset controller by toggling bit. It is a hard time for each device to add its own compatible to the driver. Since this device share a common design, it is possible to add a common device to reduce these unnecessary change. Add common binding for these kind generic reset controller.
