Some of the i.MX8MQ domains have an additional control bit in the PU handshake (HSK) register. Documentation about this bit is a bit sparse at the moment, but it seems that it controls a power-down request to the AMBA domain bridge (ADB-400) attached to those domains. As the documentation doesn't desribe the usage of this bit yet, handle it in the same way as done in the ATF implementation.
