This property will stop the LDO regulator from switching to 1.8V when the MMC core detects an UHS SD Card. VDDSDMMC power rail is used by all the SDMMC interface pins in GPIO mode (PA0 - PA13). On this board, PA10 is used as GPIO to enable the power switch controlling USB Vbus for the USB Host. The change is needed to fix the PA10 voltage level to 3.3V instead of 1.8V.
