[0/2] mips: realtek: Add reboot support

Message

The system reboot on the cameo-rtl9302c (and presumably many other boards based
on the realtek reference design) is connected via the switch reset register
(RST_GLB_CTRL_0).

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).
