Fix W=1 warning. The table uni_tdm_hw is declared in a header included by multiple C file. This isn't really a good practice but for now using __maybe_unused makes the following warning go away.

Thanks for the patch, Seems that the same patch has already been proposed by Lee: https://www.spinics.net/lists/arm-kernel/msg820327.html
