powerpc/85xx/86xx: some refactoring for fsl_uli1575 code
- Get rid of uses_fsl_uli_m1575, it does not scale for all cases. Instead, let's explicitly use machine_is() for each fixup. - Factor out MPC8610HPCD quirks to fsl_uli1575, and protect them with machine_is(). One step closer to multiplatform kernels. - Actually use fsl_uli1575 on MPC8610HPCD, so RTC quirk will be applied. - RTC quirk applies to all boards though, so no machine_is() checks.
