One of the new features of GICv4.1 is to allow virtual SGIs to be directly signaled to a VPE. For that, the ITS has grown a new 64kB page containing only a single register that is used to signal a SGI to a given VPE. Add a second mapping covering this new 64kB range, and take this opportunity to limit the original mapping to 64kB, which is enough to cover the span of the ITS registers.
Yes, no need to do ioremap for the translation register.
