media: dt-bindings: qcom,sc7280-venus: drop non-PAS support
The only users of the non-PAS setup on SC7280 platform are the ChromeOS
devices, which were cancelled before reaching end users. Iris, the
alternative driver for the same hardware, does not support non-PAS
setup. It is expected that in future both Venus and Iris devices will
use different ABI for non-PAS (EL2) setup.
In order to declare only the future-proof hardware description drop
support for non-PAS setup from the SC7280 Venus schema (breaking almost
non-existing SC7280 ChromeOS devices).
The dropped iommus entry reflects the extra stream, which should not be
treated in the same way as the main one (which doesn't match the usage
described by the iommus definition).
