doc: stm32mp1: add page for device tree bindings
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.
