Name the regulators according to the voltage rails they are feeding in
the schematic. The USB 2-4 regulators are fixed regulators and are always
on, as they are not a VBUS supply for a single USB host port on the i.MX6,
but supply VBUS to ports behind a USB hub and there is currently no way
to model this in mainline.

The Colibri default which enables USB Host power is not necessarily
tied to the OTG2 controller, some carrier board use the pin to
control USB power for both controllers. Hence name the pinctrl
group more generic.

Also move the regulator to the generic eval-v3 device tree since
the regulator is always on the carrier board. In the Colibri iMX7S
case the regulator is just not used.  This allows to reuse the
regulator in a upcoming SKU Colibri iMX7D 1GB with eMMC.
