I'm not quite sure how ethernet tuning parameter
are working in other setup and this seems the
correct way to use it
Changes in v3:
- add sgtl audio support
- add ethernet gigabit tuning
- use hub reset only in usbhub and not
in otg vbus
Changes in v2:
- add the board in alphabetic order
- remove cpu operating point
- remove simple-bus and adjust regulaotor
- add gpios to correct pinctrl
- remove no mainline binding of gpc
