Merge patch series "Clean-up patch set for MbedTLS integration"

Raymond Mao <raymond.mao@linaro.org> says:

This patch set is picked from the previously posted serie:
"[RFC] Integrate MbedTLS v3.6 LTS with U-Boot"

They are not directly related to MbedTLS integration, but the
prerequisite for a few clean-up, refactoring and minor fixes.

For V2, the linker script patch is dropped and added one patch
to move the snprintf to stdio.h
