[PATCH 2/3] ARM64: add tegra-vi support in T210 device-tree

[Bryan Wu <pengw-DDmLM1+adcrQT0dZR+AlfA@public.gmane.org>]

Following device tree support for Tegra VI now:
 - "vi" node which might have 6 ports/endpoints
 - in TPG mode, "vi" node don't need to define any ports/endpoints
 - ports/endpoints defines the link between VI and external sensors.
