In case the DHSOM is in suspend state and either reset button is pushed or IWDG2 triggers a watchdog reset, then DRAM initialization could fail as follows:
" RAM: DDR3L 32bits 2x4Gb 533MHz DDR invalid size : 0x4, expected 0x40000000 DRAM init failed: -22 ### ERROR ### Please RESET the board ### "
Avoid this failure by not keeping any Buck regulators enabled during reset, let the SoC and DRAMs power cycle fully. Since the change which keeps Buck3 VDD enabled during reset is ST specific, move this addition to ST specific SPL board initialization so that it wouldn't affect the DHSOM .

I don't see this one in 2023.07 yet, can you please pick it and send PR?
Sadly, this bugfix has not made it into 2023.07, even though the fix was posted a month and half before the actual release.
