Add node for SOR power-domain for Tegra210 and populate the SOR power-domain phandle for SOR and DPAUX nodes that are dependent on this power-domain. Please note that although neither the SOR or DPAUX drivers currently support runtime power-management, by populating the power-domain node the SOR power-domain will be turned on before probing SOR or DPAUX devices and kept on while the devices are bound.
