Add no-1-8-v property to sdmmc0 node to keep VDDSDMMC power rail at 3.3V.
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).

PA6 and PA10 GPIOs are used to enable the power switch controlling USB
Vbus for the USB Host.
