BSP driver for STM32H743I/753I -EVAL, fix for using LEDs without the I2C I/O extender

[pavel-a]

This patch fixes LEDs directly connected to GPIOs when the I2C I/O extender is disabled. File: Drivers/BSP/STM32H743I-EVAL/stm32h743i_eval.c

https://github.com/STMicroelectronics/STM32CubeH7/blob/e9472e471cc8974c4a2596fc86e565241871c20e/Drivers/BSP/STM32H743I-EVAL/stm32h743i_eval.c#L99-L108 Describe the set-up

• Board: STM32H743I/753I EVAL-2
• IDE: any (I used CubeIDE)

Describe the bug I needed to reuse the I2C for the I/O extender for other purpose, so removed #define USE_BSP_IO_CLASS Then two LEDs connected directly to MCU (red and green) stopped working.
Fix proposed below.
Maybe this applies to other similar boards.

How To Reproduce see above

Additional context

The fragment above should be:

static const  uint32_t LED_PIN[LEDn] = {LED1_PIN,
#if (USE_BSP_IO_CLASS > 0)
                                        LED2_PIN,
#else
                                       0,
#endif
                                        LED3_PIN,
#if (USE_BSP_IO_CLASS > 0)
                                        LED4_PIN
#else
                                       0,
#endif
                                       };
