The device memory SystemAllocator allocates device addresses past the end of physical memory. If a device tries to actually use this address to register a new PCI BAR, the kernel will fail with a "can't claim BAR, no compatible bridge window" error. On ARM, the kernel must be informed of where PCI bars are allowed to be allocated through the Device Tree. This CL adds a new PCI memory region to the fdt for device memory. BUG=chromium:936567 TEST=see CL:1493014. Run on ARM.
