cp.b is used a lot as a way to load binaries to memory and execute them, however we may need to integrate this with the efi subsystem to set it up as a bootdev.
So, introduce a loadm command that will be consistent with the other loadX commands and will call the efi API's.
ex: loadm $kernel_addr $kernel_addr_r $kernel_size
with this a kernel with CONFIG_EFI_STUB enabled will be loaded and then subsequently booted with bootefi command.

There's likely a spot under doc/ that needs updating now too, as we move to having better documentation.

Load a binary over memory mapped.
We don't make new commands default y for everyone, that adds to every board. This also needs a test, and should be enabled in sandbox so it is tested and also passed through coverity.
