This change fixes below sparse error:

drivers/ssb/main.c:94:16: warning: symbol 'ssb_sdio_func_to_bus'
was not declared. Should it be static?

To me this looked like an odd way to silence that warning. So I dug a
bit further.

ssb_sdio_func_to_bus() was added in commit 24ea602e183c ("ssb: Implement
SDIO host bus support"). So it was added in release v2.6.32. I found no
evidence this function was ever used. Can't it be removed?

Thanks Paul for review. Initially I too had greped for this function in
kernel and found noone using it. But I thought this function might be
useful in future. About removing it, may be original author can tell.
