Subject: [PATCH v5 1/8] dt-bindings: counter: Add new ti,am62-eqep compatible

Add new compatible ti,am62-eqep for TI K3 devices. If a device
uses this compatible, require power-domains property.

Since there is only one functional and interface clock for eqep,
clock-names is not really required, so removed from required
section, make it optional for ti,am3352-eqep compatible, and
update the example.

The clock-name also changed for TI K3 SoCs so do not allow
clock-names property for the new compatible.
