Subject: [PATCH] ARM64/irqchip: Make ACPI_IORT depend on PCI again

ACPI_IORT lost it's explicit dependency on PCI in c6bb8f89fa6df
("ARM64/irqchip: Update ACPI_IORT symbol selection logic") where the
author has relied on the general dependency of ACPI on PCI.

However, that dependency was finally removed in 5d32a66541c4 ("PCI/ACPI:
Allow ACPI to be built without CONFIG_PCI set") and now ACPI_IORT breaks
when we try and build it without PCI support.

This patch brings back the explicit dependency of ACPI_IORT on PCI.

Fixes: 5d32a66541c4 ("PCI/ACPI: Allow ACPI to be built without CONFIG_PCI set")
