In this commit, a very simple firmware management protocol driver is implemented. It will take a common FIT image firmware in a capsule file and apply the data using dfu backend storage drivers via update_fit() interface.
So "dfu_alt_info" variable should be properly set to specify a device and location to be updated. Please read README.dfu.
Fit image is a common file format for firmware update on U-Boot, and this protocol works neatly just as a wrapper for one.

Like we had discussed this offline, I don't think that efi_firmware.c name accurately represents that the file is implementing the firmware management protocol. This can be changed to efi_fmp.c, or if you don't prefer acronyms, efi_firmware_mgmt_protocol.c
I think that efi_firmware is a good prefix without any confusion given that there is no other features related to "firmware".
