drm: Remove the unused prefix in DRM_DEBUG_KMS/DRIVER/MODE

We will have to add a prefix when using the macro defintion of DRM_DEBUG_KMS
/DRM_DEBUG_DRIVER/MODE. It is not convenient. We should use the DRM_NAME
as default prefix.
So remove the prefix in the macro definition of DRM_DEBUG_KMS/DRIVER/MODE.
