meta-nuvoton: add program-edid recipe

Add program-edid recipe to support program default EDID data to
internal SMB module as I2C EEPROM when we use DVO.

reference Linux dts:

  &i2c11 {
    status = "okay";
    slave_eeprom:slave_eeprom@40000050 {
      compatible = "slave-24c02";
      reg = <0x40000050>;
      status = "okay";
    };
  };
