The value passed to LL_RCC_SetAPB2Prescaler is incorrect

Describe the set-up

Board: NUCLEO-G431RB
STM32CubeG4: v1.2.0
Compiler and its version: arm-none-eabi-gcc (xPack GNU Arm Embedded GCC, 32-bit) 9.2.1 20191025 (release) [ARM/arm-9-branch revision 277599]

Describe the bug
LL_RCC_SetAPB2Prescaler is called in Projects/NUCLEO-G431RB/Examples_LL/UTILS/UTILS_ConfigureSystemClock/Src/main.c to set the APB2 prescaler on this line:

  LL_RCC_SetAPB2Prescaler(LL_RCC_APB1_DIV_1);

The value passed to LL_RCC_SetAPB2Prescaler is LL_RCC_APB1_DIV_1 which is incorrect. The correct value to pass to LL_RCC_SetAPB2Prescaler is LL_RCC_APB2_DIV_1.

At the end of the day this doesn't actually cause any problems because both LL_RCC_APB1_DIV_1 and LL_RCC_APB2_DIV_1 are defined as 0. However, it would still make sense to use LL_RCC_APB2_DIV_1 rather than LL_RCC_APB1_DIV_1 when appropriate.

Additional context
There are several other occurrences of this issue in the code.

Hi @fivdi,

Thank you for this report, once again. This issue has been reported to the CubeMX team. A fix will be available in a future CubeMX release.

As this is a CubeMX-related issue and not directly related to the firmware published in this repository, please allow me to close it. Thank you for your comprehension and contribution.

With regards,
