Previously ACP SOF firmware used to enable the ACP external global interrupt register. This will restrict to report ACP host interrupts only after firmware loading is successful. This register needs to be set from host driver to handle other ACP interrupts(SoundWire Interrupts) before loading the ACP firmware.
Add field for external interrupt enable register in acp descriptor structure and enable the external interrupt enable register.
