In the schematics of document UM2033, 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.

Replace node name by vcc-3v3. If no v9 sent, I'll do it directly.
