Cannot build the module due to devicetree error

Nobody has claimed this yet.

## Issue template

- Hardware description: olimex_stm32_e407
- RTOS: Zephyr
- Installation type: micro_ros_zephyr_module
- Version or commit hash: 3.1.3-8-g96ab3c1

#### Steps to reproduce the issue
I'm trying to build the module for my Olimex board. This is the command I've used `west build -b olimex_stm32_e407 micro_ros_zephyr_module/`

#### Expected behavior

#### Actual behavior

This build is not successful. This is the error:

-- Found BOARD.dts: /home/vboxuser/zephyrproject/zephyr/boards/olimex/stm32_e407/olimex_stm32_e407.dts
-- Found devicetree overlay: /home/vboxuser/zephyrproject/zephyr/micro_ros_zephyr_module/app.overlay
devicetree error: Label 'zephyr_udc0' appears on /soc/usb@40040000 and on /soc/usb@50000000

#### Additional information

Start by reproducing the reported west build command for olimex_stm32_e407 and inspect the referenced board DTS and app.overlay files. Trace the duplicate zephyr_udc0 labels reported for the two USB nodes; done means the module configures and builds successfully without the devicetree error.
