- update HAL_HASH_MODE_Start_IT() functions (Mode stands for MD5, SHA1, SHA224 and SHA256 ) to :

- Fix processing fail for small input buffers
- to unlock the process and call return HAL_OK at the end of HASH processing to avoid incorrect repeating software
- properly to manage the HashITCounter efficiency
- Update to call the HAL_HASH_InCpltCallback() at the end of the complete buffer instead of every each 512 bits

- update HASH_IT_DINI and HASH_IT_DCI definition
- update __HAL_HASH_GET_FLAG() macro definition

- HAL I2S update

- update HAL_I2S_Transmit() function to ensure the waiting on Busy flag in case of slave mode selection

- HAL RTC update

- update HAL_RTCEx_SetWakeUpTimer() and HAL_RTCEx_SetWakeUpTimer_IT() functions to properly check on WUTWF flag
- rename RTC_TIMESTAMPPIN_PI8 define to RTC_TIMESTAMPPIN_POS1
- rename RTC_TIMESTAMPPIN_PC1 define to RTC_TIMESTAMPPIN_POS2
- update __HAL_RTC_WAKEUPTIMER_CLEAR_FLAG() macro definition
- update __HAL_RTC_TAMPER_GET_IT() macro definition
- update __HAL_RTC_TAMPER_CLEAR_FLAG() macro definition
- update __HAL_RTC_TIMESTAMP_CLEAR_FLAG() macro definition
- update __HAL_RTC_TAMPER_TIMESTAMP_EXTI_GET_FLAG() macro definition
- add RTC_TAMPCR_TAMPXE and RTC_TAMPCR_TAMPXIE defines

- HAL SMARTCARD update

- add SMARTCARD_FLAG_IDLE, SMARTCARD_IT_IDLE and SMARTCARD_CLEAR_IDLEF defines

- HAL UART update

- update HAL_UART_DMAResume() function to clear overrun flag before resuming the Rx transfer
- update UART_FLAG_SBKF definition

- HAL USART update

- update HAL_USART_DMAResume() function to clear overrun flag before resuming the Rx transfer

- LL FMC update

- update NAND timing maximum values

- LL USB update

- USB_FlushTxFifo API: update to flush all Tx FIFO
- Update to use local variable in USB Host channel re-activation
