gf-versions: add support for reading u-boot version from devicetree

This commit

• checks the device tree for the bootloader version
• adds a special handling when comparing bootloader versions: old u-boot versions (2020.04) will be evaluated as smaller than newer fng-system-styled bootloaders version (36.0.2)
• adds the missing yocto function to the usage docs
• adds the missing list function to the args parser
