ARM: dts: stm32: rename mmc_vcard to vcc-3v3 on stm32f746-disco

Browse Source 
commit e4e724099f04072053cf411456e3e9aae48c4af1 Linux upstream.

In the schematics of document UM1907, the power supply for the micro SD
card is the same 3v3 voltage that is used to power other devices on the
board. By generalizing the name of the voltage regulator, it can be
referenced by other nodes in the device tree without creating
misunderstandings.

This patch is preparatory for future developments.
