m68k: bitops: Fix find_*_bit() signatures

Browse source 
[ Upstream commit 6d5674090543b89aac0c177d67e5fb32ddc53804 ]

The function signatures of the m68k-optimized implementations of the
find_{first,next}_{,zero_}bit() helpers do not match the generic
variants.

Fix this by changing all non-pointer inputs and outputs to "unsigned
long", and updating a few local variables.
