With device tree binding migration to yaml it is difficult to synchronize
the binding from Linux kernel to U-Boot.

Instead of maintaining the same dt bindings, this patch adds in the U-Boot
documentation the path to the device tree bindings in Linux kernel for
STMicroelectronics devices, when they are used without modification.

- doc/
- Documentation/

The Documentation directory only contains device tree bindings related
content, so move the 3 files to doc/device-tree-bindings/.
