ES8328 and ES8388 codecs are I2C or SPI devices, thus they are addressable on their bus and 'reg' property should be always provided. Requiring 'reg' is pretty close to redundant, because the I2C and SPI controller/bus bindings require it already, but the convention is to mention 'reg' also in the device schemas.
