drm/tilcdc: Modernize driver initialization and cleanup paths

Refactor the driver initialization to use modern DRM managed resource
APIs, simplifying the code.

The tilcdc_init and tilcdc_fini wrapper functions are removed since they
served no purpose after the component framework was eliminated. Their
logic is integrated directly into probe and remove.

Key changes:
- Use devm_drm_dev_alloc() instead of drm_dev_alloc().
- Use drmm_mode_config_init() instead of drm_mode_config_init().
- Align the remove path with the probe error path to ensure consistent
  cleanup ordering in both success and failure cases.
- Adjust platform_set_drvdata() to store the private structure instead
  of the drm_device, matching the new allocation pattern.

These changes reduce error-prone code while maintaining the same
functional behavior.
