Add device tree entries for the 3 USB controllers and PHYs and
enable the third controller on Cardhu and Beaver boards.
Fix VBUS regulator entries on Beaver. The GPIO pins were wrong.
Also, a third GPIO is required to power the pullup resistors that drive
the VBUS voltage switches, so add an regulator entry for that.
