The MultiMedia audio routes can be deduced from other parts of the
device tree (e.g. the definitions of the MultiMedia DAIs) and therefore
specifying them again in "audio-routing" is redundant and prone to
mistakes. This is no longer necessary since commit 6fd8d2d2
("ASoC: qcom: qdsp6: Move frontend AIFs to q6asm-dai").

Let's drop them from the example in the DT schema as well
to avoid confusion.
