Add drm_gem_is_imported() that tests if a GEM object's buffer has been imported. Update the GEM code accordingly. GEM code usually tests for imports if import_attach has been set in struct drm_gem_object. But attaching a dma-buf on import requires a DMA-capable importer device, which is not the case for many serial busses like USB or I2C. The new helper tests if a GEM object's dma-buf has been created from the GEM object.
