Enabling the GPU power domain requires that the GPU regulator is enabled. The regulator is enabled at boot time, but gets disabled automatically when there are no users. This means the system might run into a failure state hanging the whole system for the following use cases: * if the GPU driver is being probed late (e.g. build as a module and firmware is not in initramfs), the regulator might already have been disabled. In that case the power domain is enabled before the regulator. * unbinding the GPU driver will disable the PM domain and the regulator. When the driver is bound again, the PM domain will be enabled before the regulator and error appears. Avoid this by adding an explicit regulator dependency to the power domain.
