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.

Rename the led sub nodes according to devicetree specification and
leds-gpio.yaml and for aks-cdu add label property and use the old node
name as value to stay stable and avoid breaking the userspace applications
that depend on those paths.
