Iris driver doesn't support non-PAS/TZ setup for setting up the Iris
core. It's expected that the ABI that is going to be used in a long-term
would be different from the defined venus-firmware subnode.

Granted that the SC7280 Chromebooks were cancelled before reaching wide
audience and granted the feature ABI changes, drop venus configuration
for SC7280 ChromeOS devices.

As far as I'm aware, anyone still using a sc7280 Chromebook dev
platform doesn't care about the video encoder / decoder working.
