dai: intel: hda: Add power management
This patch addresses the following issues with the Intel HDA DAI driver: 1. Adds power management support for the HDA DAI driver by implementing the `hda_pm_action` function and integrating it with the Zephyr power management framework. 2. Ensures balanced calls to `pm_device_runtime_get` and `pm_device_runtime_put` by modifying the `probe` and `remove` functions to use these power management calls. 3. Ensures that the io0 power domain is active when the HD Audio is in use by assigning the correct power domain to the HDA DAI devices in the device tree files for various Intel ADSP platforms (ace15_mtpm, ace20_lnl, ace30, ace30_ptl). 4. Enables runtime power management for the HDA DAI devices by adding the `zephyr,pm-device-runtime-auto` property in the device tree. These changes ensure that the HDA DAI driver properly manages power states, reducing power consumption and improving system stability, while ensuring the io0 power domain is active when required.
