[PATCH 12/12] util: Remove unused ffsl() function

[David Gibson <david@gibson.dropbear.id.au>]

We supply a weak alias for ffsl() in case it's not defined in our libc.
Except.. we don't have any users for it any more, so remove it.

make cppcheck doesn't spot this at present for complicated reasons, but it
might with tweaks to the options I'm experimenting with.
