drm/tegra: sor: Implement pad clock for all SOR instances
So far the pad clock was only needed on the second SOR instance. The clock does exist for all SOR instances, though, so make sure it is always implemented. This prepares for further unification of the code in subsequent patches. Signed-off-by: Thierry Reding <treding@nvidia.com>
