Fix this by modeling the NVDEC domain as a subdomain of NVJPG. This fixes the system resetting when attempting to boot NVDEC. This commit also requires a change to the PMC driver: "soc/tegra: pmc: Support nested PMC power domains". Without it, the PMC driver fails to find the parent while still registering powergates and defers its probe indefinitely.
