It is not backwards-compatible with the A31 programming model: the control register has a pulse capture mode field (bits [7:6]) that resets to a value which captures no pulses at all, and the sample clock divider is now selectable via SPLCFG bits [1:0] instead of being fixed at the old module clock / 64. Since a kernel driving it as an A31 CIR receives nothing, add the compatible as a standalone entry rather than under the allwinner,sun6i-a31-ir fallback.
