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 2 patches in this series fix a crash due to
stack overflow which is observed when running the UEFI
shell command 'dmpstore'.

The changes can be seen at:

Sami Mujawar (6):
  ArmPkg: Configure PcdEmuVariableNvModeEnable as a dynamic PCD
  ArmVirtPkg: Define variables for emulating runtime variables
  ArmVirtPkg: Fallback to variable emulation if no CFI is found
  ArmVirtPkg: Dispatch variable service if variable emulation is enabled
  ArmVirtPkg: Kvmtool: Increase primary core stack size
  ArmVirtPkg: ArmVirtQemuKernel: Increase primary core stack size
