aarch64: introduce platform interrupts module
The interrupts module is the platform specific implementation for the
interrupt controller. The Hypervisor codebase is interrupt controller
agnostic. Though for the SPMC there is some control of the GIC needed.
First helpers added are GIC priority mask register adjustement, needed
later by the managed exit scenario.
