[PATCH v5 14/25] drm/tilcdc: Use drm_module_platform_driver() helper

["Kory Maincent (TI.com)" <kory.maincent@bootlin.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.
