[PATCH v2 10/21] drm/tilcdc: Set DRIVER_ATOMIC and use atomic crtc helpers

[Jyri Sarha <jsarha@ti.com>]

Set DRIVER_ATOMIC and use atomic helpers and rename commit and prepare
crtc helpers to enable and disable. This makes the final jump to mode
setting, but there is lot of obsolete code to clean up.
