x86/intel/lpss: Make PCI dependency explicit

After commit 5d32a66541c4 (PCI/ACPI: Allow ACPI to be built without
CONFIG_PCI set) dependencies on CONFIG_PCI that previously were
satisfied implicitly through dependencies on CONFIG_ACPI have to be
specified directly.

LPSS code relies on PCI infrastructure but this dependency has not
been called out explicitly yet.
