These TODO empty code are added by
commit 9442e5b58edb ("b43: N-PHY: partly implement SPUR workaround"). It's
been more than a decade now. I don't think anyone who wants to perfect
this workaround can follow this TODO tip exactly. Instead, it limits them
to new thinking. Remove it will be better.

No functional change.

Sorry, I have compiled it. I guess it's probably separated by macros, which I didn't notice. I will check it.
