Issue

Power domain clocks get enabled in the firmware needed for the display to work, but later turned off by the kernel for power management because those clocks are not consumed by anyone - typical power management stuff. But, further late in the kernel bootup, some of those clocks are needed for the display to work. And since those are already turned off and there is no kmod (Jetson specific driver) to turn them on again, made a display non-functional. Moving the turning-off unused clocks part late in the boot-up to give enough time to probe consumer drivers to use those clocks so that they don't get turned off.
