[RFC v4 13/21] media device: Deprecate media_device_{init,cleanup}() for drivers

[Sakari Ailus <sakari.ailus@linux.intel.com>]

Drivers should no longer directly allocate media_device but rely on
media_device_alloc(), media_device_get() and media_device_put() instead.
Deprecate media_device_init() and media_device_cleanup().
