[PATCH v8 02/10] dt-bindings: clock: qcom,milos-videocc: Add missing power-domains support

[Taniya Das]

The Milos video clock controller requires the CX and MX power
domains, along with their performance state votes, to be enabled
before the clock controller can be accessed.

Document the 'power-domains' and 'required-opps' properties and add
them to the required properties list and example. Since these
properties become required for the already-documented
qcom,milos-videocc compatible, this is an ABI break for any devicetree
using this binding without specifying them.
