rcar: src: skip disabled-SRC nodes
The current device tree representation of the R-Car Sample Rate Converters
(SRC) assumes that they are numbered consecutively, starting from 0. Alas,
this is not the case with the R8A7794 SoC where SRC0 isn't present. In
order to keep the existing device trees working, I'm suggesting to use a
disabled node for SRC0. Teach the SRC probe to just skip disabled nodes.
