Subject: [PATCH v2 1/5] ARM: sun8i: r40: add USB host port nodes for R40

From: Icenowy Zheng <icenowy@...c.xyz>

Allwinner R40 SoC features a USB OTG port and two USB HOST ports.

Add support for the host ports in the DTSI file.

The OTG controller still cannot work with existing compatibles, and needs
more investigation. So it's not added yet.

Signed-off-by: Icenowy Zheng <icenowy@...c.xyz>

Changes in v2:
- Dropped the bogus OHCI resources in EHCI device node.
