serial: stm32: group dma pause/resume error handling into single function
Create new function "stm32_usart_dma_pause_resume" that called dmaengine_
pause/resume and in case of error, terminate dma transaction.
Two other functions are created to facilitate the use of stm32_usart_dma
_pause_resume : stm32_usart_tx_dma_pause, stm32_usart_tx_dma_resume.
Equivalent functions for rx will be added in future patch.
