Antonio Nino Diaz 6a23356c4f 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.

Yann Gautier 7839a05090 stm32mp1: Add clock and reset support
The clock driver is under dual license, BSD and GPLv2.
The clock driver uses device tree, so a minimal support for this is added.
The required files for driver and DTS files are in include/dt-bindings/.
