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.

I've got patches queued in my drm-tegra tree to add support for runtime
PM for the SOR driver. Will that in some way clash with this work if
merged in parallel?

Yes I had seen those. I was wondering if I should include them here but
opted not too (as it was becoming a massive series). It should be fine
to enable RPM later, you just need to be aware that the partition could
turn off on a RPM put so you just need to ensure that any register
context is saved and restored.

By the way, one item I am not certain about is the relationship between
the HDMI device and the SOR device. If the HDMI is in the SOR partition
it should also have the SOR power-domain populated, but it just uses the
SOR, then the SOR driver should handle this.

Cheers
Jon
