Add support for Interrupts to be translated by the GIC-600
Interrupt Translation Service (ITS).
ITS provides a software mechanism for translating message-based
interrupts into Locality-specific Peripheral Interrupts (LPIs).
This is based on prior work from XiaoDong Huang and
Peter Geis fixing this issue specifically for Rockchip 356x.
Plus comments of Robin Murphy about Non-Coherent properties.
