+   *Fix SDIO polling mode data transfer issues
+     Fixes two related issues in the STM32U5 SDIO driver: incorrect block count calculation 
+     that caused the card to hang, and improper buffer size handling that led to misaligned FIFO writes. 
+     Together, these changes ensure correct and stable data transfer in polling mode.
