ArmPlatformPkg/ArmJunoDxe: Set the platform dependent FDT device path
The MIDR register of the CPU on which the UEFI firmware is running on
is used to infer if the platform is a Juno r0 or a Juno r1. The right
device path to the platform FDT is then stored in the
"gEmbeddedTokenSpaceGuid.PcdFdtDevicePaths" dynamic PCD.
