[PATCH v3 2/3] arm64: dts: qcom: sc7280: Move video-firmware to chrome-common

[Luca Weiss]

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. We also need to move the secure SID 0x2184
for iommu since (on some boards) we cannot touch that.

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