For STMG4 MCUs, the peripheral registers for DAC have to be accessed by words (32bits) because DAC is connected to AHB directly. (This requirement is also there for other MCU series. However, if DAC is connected to APB like F4/L1/L4 MCUs, AHB byte or half-word transfer is changed into a 32-bit APB transfer. This means that PSIZE does not have to be DMA_PDATAALIGN_WORD on these MCUs, and in fact must be BYTE/HALFWORD to function correctly.) Fixes issue #9563.
