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.

+U-Boot device tree bindings
+----------------------------
+
+The U-Boot specific bindings are defined in the U-Boot directory:
+doc/device-tree-bindings

+* clock
+ - :download:`clock/st,stm32mp1.txt <../../device-tree-bindings/clock/st,stm32mp1.txt>`
+* ram
+ - :download:`memory-controllers/st,stm32mp1-ddr.txt <../../device-tree-bindings/memory-controllers/st,stm32mp1-ddr.txt>`
+
+All the other device tree bindings used in U-Boot are specified in Linux
+kernel. Please refer dt bindings from below specified paths in the Linux
+kernel binding directory = Documentation/devicetree/bindings/
