Precedence: bulk

If the video-firmware node is present, the venus driver assumes we're on
a system that doesn't use TZ for starting venus, like on ChromeOS
devices.

Move the video-firmware node to chrome-common.dtsi so we can use venus
on a non-ChromeOS devices.

At the same time also disable the venus node by default in the dtsi,
like it's done on other SoCs.
