Ick. This driver is littered with CONFIG_OF checks. Yet I've just seen a
patch to pxa3xx_nand which *removes* ifdefs, on the basis that all the
of_match_ functions/macros will just 'do the right thing'. Can't we do
that here too? We might just need to add __maybe_unused?

Also, why doesn't this one appear in a MODULE_DEVICE_TABLE() ?
