The broadcom settop SoCs have hardware semaphores as part of "sundry" IP block which has other controls that do not belong anywhere else. e.g. pin/mux controls, SoC identification, drive strength, reset controls, and other misc bits are part of this block.
Adding brcmstb-hwspinlock bindings which allows the hwspinlock driver to iomap only the 16 hardware semaphore registers that are part of all settop SoCs. Hence the bindings shall use the common "brcm,brcmstb-hwspinlock" compatibility string.
