[PATCH v8 01/10] dt-bindings: clock: qcom,milos-camcc: Add missing power-domains support

[Taniya Das]

The Milos camera 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-camcc
compatible, this is an ABI break for any devicetree using this binding
without specifying them.

Fixes: dbb9d53b7197 ("dt-bindings: clock: qcom: document the Milos Camera Clock Controller")
