dts: xtensa: intel_adsp: ace15: Update power domain for hda link nodes

Changing the power domain from 'hst_domain' to 'io0_domain' for the HDA
DMA link in/out nodes. This aligns the power domain assignments with the
actual hardware configuration and ensures that the power management
subsystem can accurately manage the power states of these interfaces.
