ARM: dts: stm32: use the same 3v3 for SD and DSI nodes on stm32f469-disco
In the board schematic, the power supply for the SD card is the same 3.3 volts used to power the LCD panel and other peripherals. By generalizing the name of the voltage regulator, it simplifies the device tree and makes it more readable.
