This series introduces some changes to assure the correct resource release on the V3D driver, especially the mutex. Currently, the V3D has no mutex_destroy() calls, which means that a mutex is being instantiated, but it is not being released by the end of its use. So, use the DRM-managed mutex_init variants when possible to manage the mutex release and add mutex_destroy() calls when not possible.
