ASoC: SOF: amd: clear dsp to host interrupt status

DSP_SW_INTR_STAT_OFFSET is a common interrupt register which will be
accessed by both ACP firmware and driver. This register contains register
bits corresponds to host to dsp interrupts and vice versa.

when dsp to host interrupt is reported, only clear dsp to host
interrupt bit in DSP_SW_INTR_STAT_OFFSET.
