[PATCH v4 14/25] drm/tilcdc: Use drm_module_platform_driver() helper

[Kory Maincent (TI.com)]

Use the drm_module_platform_driver() helper macro to simplify driver
registration. This macro handles both the platform driver registration
and the drm_firmware_drivers_only() check, making the custom init/exit
functions unnecessary.

Change in v3:
- New patch split from previous patch of the series.
