samples: blinky pwm running on the nucleo_l4r5zi

Adding an overlay to configure the nucleo_l4r5zi for testing the pwm blinky application on red led (PB14 on nucleo board) Each has a specific pwm output from different timers/channels Signed-off-by: Francois Ramu <[email protected]> GitOrigin-RevId: 8043fb9 Change-Id: If69f9d5d32ac716e1ba9daf3ce36a868a59051d6 Reviewed-on: https://chromium-review.googlesource.com/c/chromiumos/third_party/zephyr/+/3562859 Tested-by: CopyBot Service Account <[email protected]> Reviewed-by: Keith Short <[email protected]> Commit-Queue: Keith Short <[email protected]> Tested-by: Keith Short <[email protected]>
