OCTOSPI and MDMA - STM32CubeMX bug

Hello!

I would like to report a bug. Using STM32CubeIDE 1.16.0 and the integrated STM32CubeMX 6.12.0 i encountered a bug regarding OCTOSPI and MDMA on STM32H723ZGT6 MCU. Inside HAL_SPI_Receive_DMA(handle, pdata); where the HAL_MDMA_Start_IT is called the destination and source pointers are/were swapped resulting so the DMA was writing 64 bytes into the DR register which was crashing my application. Swapping these 2 attributes fixed the issue and is now working as intended, below im adding the swapped code where the commented out line is the false one (incorrect one).
