efi: Add a command to help with shim

Browse Source 
Shim is a program which normally comes before U-Boot in the boot
process. But when the app runs first, it can sometimes chain Shim since
that is what is contained within the bootaa64.efi file, for example.

Add a simple command for dealing with shim. For now it only supports
enabling verbosity.
