uboot-mvebu: backport LibreSSL patches for older version of LibreSSL

If you would like to compile the newest version of U-boot together with the stable
OpenWrt version, which does not have LibreSSL >= 3.5, which was updated
in the master branch by commit 5451b03b7ceb2315445c683fe174e28bbdd49c2f
("tools/libressl: bump to v3.5.3"), then you need these two patches to
fix it. They are backported from U-boot repository.

This should be backported to stable OpenWrt versions.
