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. While we are here, add an example using ti,am62-eqep compatible.
