doc: Move device tree bindings documentation to doc/device-tree-bindings
Currently the U-Boot project contains 2 documentation directories: - doc/ - Documentation/ The Documentation directory only contains device tree bindings related content, so move the 3 files to doc/device-tree-bindings/. Signed-off-by: Breno Lima <breno.lima@nxp.com>

+Broadcom STB wake-up Timer
+
+The Broadcom STB wake-up timer provides a 27Mhz resolution timer, with the
+ability to wake up the system from low-power suspend/standby modes.
+
+Required properties:
+- compatible : should contain "brcm,brcmstb-waketimer"
+- reg : the register start and length for the WKTMR block
+- interrupts : The TIMER interrupt
+- interrupt-parent: The phandle to the Always-On (AON) Power Management (PM) L2
+ interrupt controller node
+- clocks : The phandle to the UPG fixed clock (27Mhz domain)
+
+Example:
+
+waketimer@f0411580 {
+ compatible = "brcm,brcmstb-waketimer";
+ reg = <0xf0411580 0x14>;
+ interrupts = <0x3>;
+ interrupt-parent = <&aon_pm_l2_intc>;
+ clocks = <&upg_fixed>;
+};
