Cube FW_F7 V1.15.0 Bug: DMA register writes fail in peripheral init functions.

CubeMX version: 5.4.0

Firmware: FW_F7 V1.15.0

IDE: Cube v1.1.0

MX_DMA_Init() is located after other peripheral init functions, causing DMA register writes to fail in the peripheral init functions as the DMA clock is not enabled.

MX_DMA_Init() should be called before any peripheral inits which access DMA registers.

Half a day wasted on that!
