Given that this node depends on vendor-signed firmware and without
firmware we're prevented from hitting sync_state, wouldn't it make sense
to leave it status = "disabled" here, and only enable it in those cases
where firmware is available and firmware-name specified?

Right I'll only enable it on the qcom dev platforms where the firmware is
already on linux-firmware.
