efi_loader: add firmware management protocol for raw image
In this commit, a very simple firmware management protocol driver is implemented. It will take a binary image in a capsule file and apply the data using dfu backend storage drivers via dfu_write_by_alt() interface. So "dfu_alt_info" variable should be properly set to specify a device and location to be updated. Please read README.dfu. Signed-off-by: AKASHI Takahiro <takahiro.akashi@linaro.org>
