Map PCI CAM MMIO region and register pages with the MMIO guard. Crosvm uses a memory-mapped Configuration Access Mechanism for PCI, which we can find in the device tree. We need to map this as device memory and register it with the hypervisor MMIO guard before trying to access any PCI devices. Bug: 237249346 Test: Ran pVM firmware manually.
