STM32 SDIO driver issue with wifi_airoc

[ondrabriza]

Describe the bug

Hello,
I am using Nucleo-stm32u575, Murrata 2AE M.2 module with LBEE0ZZ2WS-ST-NCL adapter.
I have a problem with sdhc driver, its failing CMD 8, 5 during initialization, as a result airoc is not initialized and everything fails, see Relevant log output.
I followed this pull request #89776.

Regression

• This is a regression.
