arm: dt: imx6qdl: add tqma6[qdl] som on mba6 mainboard

The device trees for TQMa6x SOM support variations in
- CPU type: imx6dl- or imx6q-
- MBa6 I2C bus access: -mba6a (i2c1) or -mba6b (i2c3)
  (plus the respective common/module include trees)

- USBH1 is directly connected to a hub
- USBOTG is connected to a separate connector
  and can act as host/device or full OTG port.
