irqchip/dw-apb-ictl: Support building as module

Browse source

The driver is now always built in. In some synaptics ARM64 SoCs it is used
as a second level interrupt controller hanging off the ARM GIC and is
therefore loadable during boot.

Enable it to be built as a module and handle built-in usage correctly, so
that it continues working on systems where it is the main interrupt
controller.
