Capsule data can be loaded into the system either via UpdateCapsule runtime service or files on a file system (of boot device). The latter case is called "capsules on disk", and actual updates will take place at the next boot time. In this commit, we will support capsule on disk mechanism. Please note that U-Boot itself has no notion of "boot device" and all the capsule files to be executed will be detected only if they are located in a specific directory, \EFI\UpdateCapsule, on a device that is identified as a boot device by "BootXXXX" variables.
