boot/arm-trusted-firmware: fix build issue with binutils 2.39+
PATCH 1/1 boot/arm-trusted-firmware: fix build issue with binutils 2.39+
The new version of binutils introduces a new warning when linking. The new warninng is enabled by default. To fix the issue this warning is disabled by adding the patches to the arm-trusted-firmware package v{2.2..2.8}. This is a backport of an upstream commit [1]
