Because the switch register block encompasses a number of functions that would normally be separate perhipherals I've represented it as a syscon node. Right now the only peripheral I've added is the reset (using syscon-reboot). The binding and syscon node will be expanded in the future to add some additional functions (e.g. I2C, GPIO, MDIO).
