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
?
There is already cpufreq-qcom-hw.txt with 'qcom,freq-domain'
and analogous purpose.
