Yann E. MORIN ff1a03ab28 boot/uboot: license files hashes only valid for latest version 
We can only know the details of the license files for known versions.  For
custom, older or newer versions, the license files may change, or may be
moved around.

So, do for U-Boot as was done for ATF, linux, and linux-headers, and only
define the list of license files for the latest version.

# Fixup inclusion of libfdt headers, which can fail in older u-boot versions
# when libfdt-devel is installed system-wide.
# The core change is equivalent to upstream commit
# e0d20dc1521e74b82dbd69be53a048847798a90a (first in v2018.03). However, the fixup
# is complicated by the fact that the underlying u-boot code changed multiple
# times in history:
# - The directory scripts/dtc/libfdt only exists since upstream commit
# c0e032e0090d6541549b19cc47e06ccd1f302893 (first in v2017.11). For earlier
# versions, create a dummy scripts/dtc/libfdt directory with symlinks for the
# fdt-related files. This allows to use the same -I<path> option for both
# cases.
# - The variable 'srctree' used to be called 'SRCTREE' before upstream commit
# 01286329b27b27eaeda045b469d41b1d9fce545a (first in v2014.04).
# - The original location for libfdt, 'lib/libfdt/', used to be simply
# 'libfdt' before upstream commit 0de71d507157c4bd4fddcd3a419140d2b986eed2
# (first in v2010.06). Make the 'lib' part optional in the substitution to
