It's called from various board files (board-omap3evm.c,
board-4430sdp.c.)

It would be my fault if I wrote those board files.  ;)

Yes, that's the workaround I'm already using, but it is not a fix.

This dependency breaks the ability to build a minimal kernel with
everything as modules (allmodconfig)

The nop xceiv needs a way for built-in code to register itself for
the cases when no xceiv is built as a module.
