Instead of relying on VirtFdtDxe to populate the GIC related PCDs, move this handling to our implementation of ArmGicArchLib, and retrieve the required DT info using the new FDT client protocol. This removes one of the reasons we need to load VirtFdtDxe first using an 'A PRIORI' declaration in the platform FDF. As Laszlo kindly confirms: So, ultimately, the only user of this library instance is "ArmPkg/Drivers/ArmGic/ArmGicDxe.inf". ... Indeed, checking the build report file for ArmVirtQemu (AARCH64), I find ArmVirtGicArchLib (and ArmGicLib too) only under "ArmPkg/Drivers/ArmGic/ArmGicDxe.inf". which means that the constructor is only invoked once, and so the dynamic PCDs are set in time for ArmGicDxe to consume them, and never afterwards.
