dma: intel_adsp_hda: re-enable interrupts upon resume

Commit fa4a9db ("dma: intel_adsp_hda: Fix invalid init sequence and
register use") moved intel_adsp_hda_channels_init() out from resume
path. This causes a regression to CONFIG_DMA_INTEL_ADSP_HDA_TIMING_L1_EXIT
as without irq_config() call the interrupt configuration may be partial.

Address this by calling irq_config() unconditionally on resume path.
