m68knommu: add ffs and __ffs plattform which support ISA A+ or ISA C
the ff1 and bitrev opcode appears in ISA C and ISA A+ what isn't
supported by all plattforms. The assembly optimization is automaticly
enabled if the compiler understand the required cpu keyword.
My m5235 seems to boot and run fine so far.
