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>

-NOP PHY driver
-
-This driver is used to stub PHY operations in a driver (USB, SATA).
-This is useful when the 'client' driver (USB, SATA, ...) uses the PHY framework
-and there is no actual PHY harwdare to drive.
-
-Required properties:
-- compatible : must contain "nop-phy"
-- #phy-cells : must contain <0>
-
-Example:
-
-nop_phy {
- compatible = "nop-phy";
- #phy-cells = <0>;
-};

-STMicroelectronics STM32 USB HS PHY controller
-
-The STM32 USBPHYC block contains a dual port High Speed UTMI+ PHY and a UTMI
-switch. It controls PHY configuration and status, and the UTMI+ switch that
-selects either OTG or HOST controller for the second PHY port. It also sets
-PLL configuration.

-Phy provider node
-=================
-
-Required properties:
-- compatible: must be "st,stm32mp1-usbphyc"
-- reg: address and length of the usb phy control register set
-- clocks: phandle + clock specifier for the PLL phy clock
-- #address-cells: number of address cells for phys sub-nodes, must be <1>
-- #size-cells: number of size cells for phys sub-nodes, must be <0>
-
-Optional properties:
-- assigned-clocks: phandle + clock specifier for the PLL phy clock
-- assigned-clock-parents: the PLL phy clock parent
-- resets: phandle + reset specifier
-
-Required nodes: one sub-node per port the controller provides.

-Phy sub-nodes
-==============
-
-Required properties:
-- reg: phy port index
-- phy-supply: phandle to the regulator providing 3V3 power to the PHY,
- see phy-bindings.txt in the same directory.
-- vdda1v1-supply: phandle to the regulator providing 1V1 power to the PHY
-- vdda1v8-supply: phandle to the regulator providing 1V8 power to the PHY
-- #phy-cells: see phy-bindings.txt in the same directory, must be <0> for PHY
- port#1 and must be <1> for PHY port#2, to select USB controller
-

-Example:
- usbphyc: usb-phy@5a006000 {

-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>;
-};
