[U-Boot] [PATCH v2 12/14] cmd: run: add "-e" option to run an EFI application

[AKASHI Takahiro]

"run -e" allows for executing EFI application with a specific "BootXXXX"
variable. If no "BootXXXX" is specified or "BootOrder" is specified,
it tries to run an EFI application specified in the order of "bootOrder."
