Add devicetree documentation for 'mediatek,freq-domain' property specific
to Mediatek CPUs. This property is used to reference the CPUFREQ node
along with the domain id.

This needs to be a common binding shared with SCMI domains.
Would it be accurate to create a new binding file:
Documentation/devicetree/bindings/cpufreq/cpufreq-mediatek-hw.txt
?
Nope, Rob already asked to unify all such bindings and generalise it.
Here is my attempt[1] and this must just use it or help to enhance that
in order to make use of that binding.
That's great. Thank you for the information.
