Since the stub version of of_dma_configure_id() was added in commit
a081bd4af4ce ("of/device: Add input id to of_dma_configure()"), it has
not matched the signature of the full function, leading to build failure
reports when code using this function is built on !OF configurations.
Fixes: a081bd4af4ce ("of/device: Add input id to of_dma_configure()")
