11 - reg : the register and size of this local arbiter.
12 - mediatek,smi : a phandle to the smi_common node.
13 - power-domains : a phandle to the power domain of this local arbiter.
14 - clocks : Must contain an entry for each entry in clock-names.
15 - clock-names: must contain 2 entries, as follows:
16 - "apb" : Advanced Peripheral Bus clock, It's the clock for setting
