ASoC: codecs: max9892x: Unify interleave mode OF property

MAX98926 and MAX98927 are quite similar and use the same bindings,
although drivers were not implementing them in the same way:
MAX98926 has boolean "interleave-mode" but MAX98927 has uint32
"interleave_mode".  Unify them under maxim,interleave-mode, already used
in other Maxim device.
