Mistake in stm32f0xx_hal_uart_ex.h, missing STM32F030xC check

[bonmotwang]

CubeMX Firmware Package: STM32Cube FW_F0 V1.10.1

CPU: STM32F030RC.

If use it ASIS, compiler will report UART_TXDATA_FLUSH_REQUEST is undefined.

Problem is in line 1: It missed STM32F030xC.

#if !defined(STM32F030x6) && !defined(STM32F030x8) 
#define __HAL_UART_FLUSH_DRREGISTER(__HANDLE__)  \
  do{                \
      SET_BIT((__HANDLE__)->Instance->RQR, UART_RXDATA_FLUSH_REQUEST); \
      SET_BIT((__HANDLE__)->Instance->RQR, UART_TXDATA_FLUSH_REQUEST); \
    }  while(0)
#else
#define __HAL_UART_FLUSH_DRREGISTER(__HANDLE__)  \
  do{                \
      SET_BIT((__HANDLE__)->Instance->RQR, UART_RXDATA_FLUSH_REQUEST); \
    }  while(0)
#endif /* !defined(STM32F030x6) && !defined(STM32F030x8) */ 

After I added STM32F030xC in the check list. It compiles OK.

#if !defined(STM32F030x6) && !defined(STM32F030x8) && !defined(STM32F030xC)
#define __HAL_UART_FLUSH_DRREGISTER(__HANDLE__)  \
  do{                \
      SET_BIT((__HANDLE__)->Instance->RQR, UART_RXDATA_FLUSH_REQUEST); \
      SET_BIT((__HANDLE__)->Instance->RQR, UART_TXDATA_FLUSH_REQUEST); \
    }  while(0)
#else
#define __HAL_UART_FLUSH_DRREGISTER(__HANDLE__)  \
  do{                \
      SET_BIT((__HANDLE__)->Instance->RQR, UART_RXDATA_FLUSH_REQUEST); \
    }  while(0)
#endif /* !defined(STM32F030x6) && !defined(STM32F030x8) */ 

The bottom line is:

STM32F030RC only has USART_RQR_RXFRQ, but not USART_RQR_TXFRQ

I hope ST can fix this error in the future.
