[PATCH v6 01/11] ACPI / LPSS: Make PCI dependency explicit

[Sinan Kaya]

After 'commit 5d32a66541c4 ("PCI/ACPI: Allow ACPI to be built without
CONFIG_PCI set")', it is possible to build ACPI without any PCI support.
This code depends on PCI. Compile only when PCI is present.

Fixes: 5d32a66541c46 ("PCI/ACPI: Allow ACPI to be built without CONFIG_PCI set")
