cmd: add efidebug command
Currently, there is no easy way to add or modify UEFI variables.
In particular, bootmgr supports BootOrder/BootXXXX variables, it is
quite hard to define them as u-boot variables because they are represented
in a complicated and encoded format.
The new command, efidebug, helps address these issues and give us
more friendly interfaces:
* efidebug boot add: add BootXXXX variable
* efidebug boot rm: remove BootXXXX variable
* efidebug boot dump: display all BootXXXX variables
* efidebug boot next: set BootNext variable
* efidebug boot order: set/display a boot order (BootOrder)
