This patch adds/enables USB2.0 peripheral for R-Car [DE]3 boards.
R-Car E3 Ebisu board connects the ID pin to the SoC, so this adds
a group "usb0_id" into usb0_pins node. Also, to use SW15 pin 3 side,
this patch adds vbus0_usb2 node on r8a77990-ebisu.dts.
R-Car D3 Draak board doesn't connect the ID pin, so this adds
"renesas,no-otg-pins" property into usb2_phy0 node.

Changed from v2:
- Use otg pin on r8a77990-ebisu board. So, I revise the commit log.
- I got Reviewed-by from Simon-san at v2. However, since I change
the integration at v3 as above. I didn't add Reviewed-by on this.
Changed from v1:
- Revise the reg size for each hsusb node.
