drm/tegra: rgb: Restore DPMS
In order to restore DPMS with atomic mode-setting, move all code from the ->mode_set() callback into ->enable(). At the same time, rename the ->prepare() callback to ->disable() to use the names preferred by atomic mode-setting. This simplifies the calling sequence and will allow DPMS code to use runtime PM in subsequent patches. While at it, remove the enabled field that hasn't been used since the demidlayering of the output drivers done in preparation for the atomic mode-setting conversion.
