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).
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.

The RTC and RTT peripherals use the timing domain slow clock (TD_SLCK),
sourced from the 32.768 kHz crystal oscillator or slow rc oscillator.
The previously used Monitoring domain slow clock (MD_SLCK) is sourced
from an internal RC oscillator which is most probably not precise enough
for real time clock purposes.
