Subject: [PATCH] boards: add usb to stm32f4_disco

This patch adds USB capabilities to the stm32f4 discovery board.
As the board has a MicroUSB port that I would like to use as stdout I
just added USB. The needed entry within pinmux.c is already there but
USB was missing in the dts file and documentation.

I tested it with the upcomming commit.
