slim: ngd: Handle Process Domain restart

Slimbus master component driver typically resides in a domain on remote
processor (ADSP). If that domain restarts, slimbus master driver
restarts reinitializing the slimbus HW.
Handle such process domain restart, and use subsystem restart if the
process domain restart is not available.
