[PULL 21/30] hw/intc/arm_gic: Un-inline GIC*/ITS class_name() helpers

[Philippe Mathieu-Daudé]

"kvm_arm.h" contains external and internal prototype declarations.
Files under the hw/ directory should only access the KVM external
API.

In order to avoid machine / device models to include "kvm_arm.h"
simply to get the QOM GIC/ITS class name, un-inline each class
name getter to the proper device model file.
