ACPI IORT is an ACPI addendum to describe the connection topology of devices with IOMMUs and interrupt controllers on ARM64 ACPI systems. Currently the ACPI IORT Kbuild symbol is selected whenever the Kbuild symbol ARM_GIC_V3_ITS is enabled, which in turn is selected by ARM64 Kbuild defaults. This makes the logic behind ACPI_IORT selection a bit twisted and not easy to follow. On ARM64 systems enabling ACPI the kbuild symbol ACPI_IORT should always be selected in that it is a kernel layer provided to the ARM64 arch code to parse and enable ACPI firmware bindings. Make the ACPI_IORT selection explicit in ARM64 Kbuild and remove the selection from ARM_GIC_V3_ITS entry, making the ACPI_IORT selection logic clearer to follow.
