Add devicetree documentation for 'qcom,freq-domain' property specific
to Qualcomm CPUs. This property is used to reference the CPUFREQ node
along with Domain ID (0/1).

There's no 3 patches doing the same thing. Mediatek and SCMI are the 
others. This will need to be common. 

This property is used by existing dtbs for Qualcomm sdm845, sm8150,
sm8250 and sc7180 based devices, so I expect that the support for the
existing property will stay.
