drm/tegra: Parse device tree earlier
Parsing the device tree may cause probing to be deferred. Doing this as early as possible prevents any other resources from being requested and enabled, therefore reducing the need to cleanup on deferred probe while at the same time not wasting precious CPU cycles determining if probing needs to be deferred or not.
