…management

This commit refactors the Intel SSP DAI driver to support dynamic
management of SSP links. The changes include the introduction of a new
structure `intel_ssp_link` to encapsulate SSP link-specific data.

Key changes:
- Add new static functions to manage SSP link power.
- Update the DAI SSP configuration functions to use the new link
  management approach.
- Update device tree bindings and instances to reflect the new SSP link
  management mechanism.

The new approach allows for more flexible and maintainable management of
SSP links.
