Add boot over DFU RAM as an alternate to running script at a fixed address like done today. The main culprit is that it's not possible to do that on G12A/Sm1 platforms due to changes in the USB boot protocol. With this, U-Boot will present a DFU device with a ram slot where the Host could write a fitImage or legacy U-Boot image, then with the detach command boot will continue trying to boot the uploaded image.
