dt-bindings:iio:adc:mediatek,mt2701-auxadc: rename and yaml conversion.
The current driver and indeed binding are named after a part that they
do not list in the compatible. Hence renamed the binding to reflect
one that does.
>From the driver it looks like there is a lot more backwards compatibility
than the binding currently reflects. We could consider expressing that
more explicitly in the yaml for the compatible property. I have
added one explicit pair that was present in the upstream dtsi files.
I added Matthias alongside Zhiyong Tao because I don't think
Zhiyong Tao has reviewed recent patches. Please let me know if this
isn't the right thing to do.
