efi_loader: add device-path utils
Helpers to construct device-paths from devices, partitions, files, and
for parsing and manipulating device-paths.
For non-legacy devices, this will use u-boot's device-model to construct
device-paths which include bus hierarchy to construct device-paths. For
legacy devices we still fake it, but slightly more convincingly.
