The Colibri Evaluation Carrier Board provides a MCP2515 CAN
controller connected via SPI. Note that the i.MX 7 provides
an internal CAN controller which is much better suited for CAN
operations. Using the MCP2515 with a Colibri iMX7 module is
mainly useful to test the SPI interface.

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.
