ASoC: rcar: skip disabled-SSI nodes
The current device tree representation of the R-Car SSI assumes that they are numbered consecutively, starting from 0. Alas, this is not the case with the R8A77995 (D3) SoC which SSI1/SSI2 aren't present. In order to keep the existing device trees working, I'm suggesting to use a disabled node for SSI0/SSI1. Teach the SSI probe to just skip disabled nodes.
