Add devicetree binding schema for the SSE-710 Host Base System Control SSE-710 is implemented by the Corstone-1000 IoT Reference Design Platform [1]. The Host Base System Control has registers to control the clocks, power, and reset for SSE-710 subsystem [2]. It resides within AONTOP power domain. The registers are mapped under the SSE-710 Host System memory map [3].
