drm: omapdrm: Remove omap_crtc enabled field
The field tracks the CRTC state to avoid double-enable or -disable. As the DRM atomic core guarantees that the CRTC enable and disable functions won't be called on an already enabled or disabled CRTC, such tracking isn't needed. Remove the enabled field.
