ACPI / LPSS: allow to use specific PM domain during ->probe()
The LPSS DMA controller would like to use the specific PM domain callbacks during early stage, namely in ->probe(). This patch moves the specific PM domain assignment early to be accessible during a whole life time of the device in the system. Suggested-by: Rafael J.
