[PATCH v2 5/7] arm/acpi: fix duplicated _UID of PCI interrupt link devic

From: Heyi Guo
Subject: [PATCH v2 5/7] arm/acpi: fix duplicated _UID of PCI interrupt link devices
Date: Mon, 3 Feb 2020 08:15:03 +0800

Using _UID of 0 for all PCI interrupt link devices absolutely violates
the spec. Simply increase one by one.
