[PATCH v1 2/4] ACPI / LPSS: allow to use specific PM domain during ->probe()

[Andy Shevchenko <andriy.shevchenko@linux.intel.com>]

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.
