Some USART2 #define seems to be missing from stm32g030xx.h, stm32g031xx.h, stm32g041xx.h
stm32g030xx.h, stm32g031xx.h, stm32g041xx.h:
these #define seems to be missing/removed from aforementioned files:
#define RCC_CCIPR_USART2SEL_Pos (2U)
#define RCC_CCIPR_USART2SEL_Msk (0x3UL << RCC_CCIPR_USART2SEL_Pos) /*!< 0x0000000C */
#define RCC_CCIPR_USART2SEL RCC_CCIPR_USART2SEL_Msk
#define RCC_CCIPR_USART2SEL_0 (0x1UL << RCC_CCIPR_USART2SEL_Pos) /*!< 0x00000004 */
#define RCC_CCIPR_USART2SEL_1 (0x2UL << RCC_CCIPR_USART2SEL_Pos) /*!< 0x00000008 */
