Ok, so here's a simple patch to save everyone trouble, I guess.

Though on the other hand I can imagine that perhaps including this generic common-board-devices.c
might not be desirable for people that don't use anything from that file.

Since the common-board-devices.c has TWL initialization I doubt there would a
board that does not use it at all...

Would it be a better idea to split it to a file-per-feature?

Splitting the common-board-devices into a file-per-feature will diminish its
added value, IMO.
We can either continue to use #ifdef CONFIG_SOMETHING in both
common-board-devices.[ch] as your fix proposes or just drop #ifdefs and inlines
from the header.
Tony, what is your preference?

We should consider the code size too.. Maybe see if you can make them
weak instead of the ifdefs?

Unless I completely misunderstand how weak works, we'll still have ifdefs in .c
file, i.e.

common-board-devices.h:

void __omap_nand_flash_init(int opts, struct mtd_partition *parts, int n_parts)
{
}

void omap_nand_flash_init(int opts, struct mtd_partition *parts, int n_parts)
__attribute__((weak, alias("__omap_nand_flash_init")));

common-board-devices.c:
#if defined(CONFIG_MTD_NAND_OMAP2) || defined(CONFIG_MTD_NAND_OMAP2_MODULE)
void omap_nand_flash_init(int opts, struct mtd_partition *parts, int n_parts)
{
...
}
#endif

Yet, we can keep the ifdefs only in common-board-devices.c and get rid if
inlines in the header.
Also, all the code in common-board-devices.c is __init, so it's eventually
dropped in runtime

Sounds OK to me for the simple platform init functions used for most
common devices.

For anything more complex, we can have a separate file with ifdef in the
header and Makefile compiling it in only as selected.

Tony
