dump_regs() is a handy function to keep around for bringing up a new dm9000-based board, but defining CONFIG_DM9000_DEBUG only adds the function - nowhere currently uses it. Rather than remove a potentially useful function, let's just tell gcc to not emit a warning when it is unused.

Please make sure we have <linux/compiler.h> and use __unused (or __maybe_unused?) here, thanks!
