Sami Mujawar 84d0b21d18 ArmVirtPkg: Fallback to variable emulation if no CFI is found ... The kvmtool option '--flash <flash filename>' is used to launch a guests VM with a CFI flash device that maps the flash file specified at the command line. However, kvmtool allows guest VMs to be launched without a CFI flash device. In such scenarios the firmware can utilize the emulated variable storage for UEFI variables. To support this the PCD gEfiMdeModulePkgTokenSpaceGuid.PcdEmuVariableNvModeEnable must be set to TRUE. Therefore, update the NorFlashKvmtoolLib to fallback to variable emulation if a CFI device is not detected. Also improve the error logging.
