dt-bindings: clock: qcom,qcm2290-dispcc: Add missing power-domains property

Browse Source 
Add the missing power-domains property to associate DISPCC with RPMPD_CX.
This is to ensure the genpd performance state votes on the GDSC to get
propagated to the CX rail and to avoid the rail under-voltage conditions.
This change breaks ABI, as the power-domains property is marked as
required.
