STM32CubeMX bug: data width is changed to Byte after you generate the code

1. Open DAC Configuration and set Data Width to ''Half Width'' .

2. Generate code. Generated stm32f7xx_hal_msp.c has following lines despite the ''Half Width'' setting.

hdma_dac1.Init.PeriphDataAlignment = DMA_PDATAALIGN_BYTE;

hdma_dac1.Init.MemDataAlignment = DMA_MDATAALIGN_BYTE;

3. Open DAC Configuration. Data width seems to be ''Half Width'', but in DMA Configuration, it's changed to ''Byte''.
