ASoC: SOF: amd: enable ACP external global interrupt

Browse source 
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.
