[PATCH v2 2/7] ACPI / LPSS: allow to use specific PM domain during ->probe()

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

This is an amendment to previously pushed commit 01ac170ba29a (ACPI / LPSS:
allow to use specific PM domain during ->probe()). We can't assign anything to
the platform device on ADD_DEVICE stage since it might be changed during
unbound / bind cycle.
