functions: skip flash-kernel in all EFI system
Even this platform is supported. if this platform is under EFI system. We don't need u-boot or flash kernel into system. Leave all kernel handling to EFI.
For example: APM Mustang could have EFI mode rather than U-boot. It could avoid fatal in flash-kernel when installing flash-kernel in EFI system.
