ASoC: SOF: amd: fix for false dsp interrupts

[ Upstream commit b9846a386734e73a1414950ebfd50f04919f5e24 ]

Before ACP firmware loading, DSP interrupts are not expected.
Sometimes after reboot, it's observed that before ACP firmware is loaded
false DSP interrupt is reported.
Registering the interrupt handler before acp initialization causing false
interrupts sometimes on reboot as ACP reset is not applied.
Correct the sequence by invoking acp initialization sequence prior to
registering interrupt handler.
