Introduce a new API function in the sdmmc_stm32 driver that allows applications to access the Card Specific Data (CSD) register of the SD/MMC card. This functionality, already available in the SPI-based SD and MMC subsystems, was previously missing from the STM32 SDMMC driver. This enhancement enables use cases such as verifying the correct SD card during manufacturing, ensuring that OEMs use the specified SD card, and preventing mismatches.
