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.
