Convert the Cirrus EP7209 UART binding to DT schema. There is no user of "cirrus,ep7312-uart" other than the example, so drop it. Drop the "aliases" node part as it is not relevant to the schema. The modem control GPIOs are covered by the serial.yaml schema and don't have to be listed in the schema.
