Subject: [PATCH v3 01/12] ARM: dts: imx7d: cl-som-imx7 imx7d-sbc-imx7: move USB

Whether and which USB port is enabled and how they
are powered is a function of the carrier board, not
of the SoM. Different carrier boards can have different
ports enabled / wired up, and power them differently;
so this should really move into the respective DTS.

Do so and update the USB power supply to reflect
the actual situation on the sbc-imx7 carrier board.
