[RESEND PATCH] ARM: dts: stm32f469-disco: use the same 3v3 for SD and DSI nodes

[Dario Binacchi]

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.
