Kvmtool allows guest VMs to be launched with or without a CFI flash device. The guest hardware configuration can be seen in the device tree that Kvmtool hands off to the guest firmware.
Therefore, add support to dynamically detect if a CFI flash device is present. If CFI is present use the NorFlashDxe driver as the backend for variable services; otherwise use emulated runtime variables. The last patch in this series fix a crash due to stack overflow which is observed when running the UEFI shell command 'dmpstore'. The first 4 patches in this series have not been modified and are resent with the v2 series.
