usb: gadget: sdp: extend images compatible for jumps
Support U-Boot images in SPL so that u-boot.img files can be
directly downloaded and executed. Furthermore support U-Boot
scripts download and execution in full U-Boot so that custom
recovery actions can be downloaded from the host in a third
step.
