It should come from review message when submit binding-doc patch.  but I
can't find it now. But at least, compatible string and node-name use "-".

It'd better to add to writing-bindings.rst. It is hard to search whole
linux-devicetree mail list or brain may cheat me. It is good to keep
everything consistent.

like:
     " vs '
     VCC-supply vs vcc-supply
     ...

core, plat is also better than hifi_core, hifi_plat
