Replace stdio.h functions by TF functions
Functions provided by stdio.h such as printf and sprintf are available in the codebase, but they add a lot of code to the final image if they are used: - AArch64: ~4KB - AArch32: ~2KB in T32, ~3KB in A32 tf_printf and tf_snprintf are a lot more simple, but it is preferable to use them when possible because they are also used in common code.
