[RFC PATCH 11/13] arm64: tegra: Add SOR power-domain node

[Jon Hunter]

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.
