drm/tilcdc: Add support for DRM_BRIDGE_ATTACH_NO_CONNECTOR

Convert the driver to use the DRM_BRIDGE_ATTACH_NO_CONNECTOR flag when
attaching bridges. This modernizes the driver by delegating connector
creation to the bridge subsystem through drm_bridge_connector_init()
instead of manually searching for connectors created by the bridge.

The custom tilcdc_encoder_find_connector() function is removed and
replaced with the standard drm_bridge_connector infrastructure, which
simplifies the code and aligns with current DRM bridge best practices.

This change is safe as there are now no in-tree devicetrees that
connect tilcdc to bridges which do not support the
DRM_BRIDGE_ATTACH_NO_CONNECTOR flag.

drm/tilcdc: Use devm_drm_of_get_bridge() helper

Replace drm_of_find_panel_or_bridge() with the newer
devm_drm_of_get_bridge() helper which simplifies the code by:
- Automatically handling both panel and bridge cases internally
- Managing the panel-to-bridge conversion when needed
- Using devres for resource management, eliminating manual cleanup

This removes the need for explicit panel-to-bridge conversion via
devm_drm_panel_bridge_add_typed() and the associated error handling path.

drm/tilcdc: Convert to DRM managed resources

Convert the tilcdc driver to use DRM managed resources (drmm_* APIs)
to eliminate resource lifetime issues, particularly in probe deferral
scenarios.

This conversion addresses potential use-after-free bugs by ensuring
proper cleanup ordering through the DRM managed resource framework.
The changes include:
- Replace drm_crtc_init_with_planes() with drmm_crtc_alloc_with_planes()
- Replace drm_universal_plane_init() with drmm_universal_plane_alloc()
- Replace drm_simple_encoder_init() with drmm_simple_encoder_alloc()
- Remove manual cleanup in tilcdc_crtc_destroy() and error paths
- Remove drm_encoder_cleanup() from encoder error handling paths
- Use drmm_add_action_or_reset() for remaining cleanup operations

This approach is recommended by the DRM subsystem for improved resource
lifetime management and is particularly important for drivers that may
experience probe deferral.

drm/tilcdc: Remove the use of drm_device private_data

The DRM core documentation recommends against using dev_private:
"Instead of using this pointer it is recommended that drivers use
embed the struct &drm_device in their larger per-device structure."

This patch refactors the tilcdc driver to follow this recommendation
by embedding struct drm_device within struct tilcdc_drm_private and
replacing all dev->dev_private accesses with the ddev_to_tilcdc_priv()
helper macro that uses container_of().

This change aligns the driver with modern DRM best practices.
