Revert "ACPI / LPSS: allow to use specific PM domain during ->probe()"
The specific power domain can't be used in a way provided by the commit
01ac170ba29a, i.e. pointer to platform device is a subject to change during
unbound / bind cycle.
This reverts commit 01ac170ba29a9903ee590e1ef2d8e6b27b49a16c.
Fixes: 3df2da968744 (Revert "ACPI / LPSS: introduce a 'proxy' device to power on LPSS for DMA")
