Subject: [PATCH v2 1/4] arm64: dts: qcom: sc7280-chrome-common: disable
 Venus

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.
