[IA64] Use asm-generic/bitops/builtin-ffs.h
The definition of ffs() for ia64 is almost the same as asm-generic/bitops/builtin-ffs.h. The only difference is whether it is defined as inline function or macro function. So this switches to use the header (both to reduce amount of arch specific code, and because inline functions provide type-checking that macros do not).
