irqchip/gic-v3-its: Workaround HiSilicon Hip07 redistributor addressing
The ITSes on the Hip07 (as present in the Huawei D05) are broken when
it comes to addressing the redistributors, and need to be explicitely
told to address the VLPI page instead of the redistributor base address.
So let's add yet another quirk, fixing up the target address
in the command stream.
