m68k: use CPU_HAS_NO_BITFIELDS for signal functions
When reworking bitops.h to be clean for all processor types we introduced a CONFIG_CPU_HAS_NO_BITFIELDS define to signal whether this processor type supported the bit field instructions. The ARCH_SIG_BITOPS functions for m68k use these instruction types. We should base the use of these functions (or the generic versions) on the CONFIG_CPU_HAS_NO_BITFIELDS define.
