This fixes a race in `LED<NUM>_TOGGLE`, which is a read-copy-write
operation. Any access to a GPIO pin on the same GPIO port that
happens concurrently could result in data corruption. Using the
GPIO LL API, which is thread-safe, fixes the issue.
Note: The used GPIO LL functions will work even in when the GPIO LL
module is not used.

* The STM32F723G-DISCO board has a 240 x 240 pixel TFT color LCD display with
|
|
* ST7789H2 driver IC using the MCU 8080 16-bit parallel interface (default with
|
|
* SB15=ON and SB16=OFF). SB15 and SB16 control the ST7789H2 `IM0` signal.
|
|
* With SB15=OFF and SB16=ON, the MCU 8080 8-bit parallel interface is enabled.
|
|
*
|
|
* For the `LCD_*` pins, please refer to the
|
|
* [schematic](https://www.st.com/resource/en/schematic_pack/mb1260-f723e-d03_schematic.pdf).
