platform/x86: ISST: Store and restore all domains data

Browse source

The suspend/resume callbacks currently only store and restore the
configuration for power domain 0. However, other power domains may also
have modified configurations that need to be preserved across suspend/
resume cycles.

Extend the store/restore functionality to handle all power domains.
