ARM: sun8i: a83t: cubietruck-plus: Enable onboard USB peripherals
The Cubietruck-plus has a GL830 USB-to-SATA bridge connected to EHCI0, and a USB3503 HSIC USB 2.0 hub connected to EHCI1. The USB3503's I2C control interface is not connected. This patch enables both EHCI controllers, adds a device node for the USB hub, and includes sunxi-common-regulators.dtsi for the VBUS regulators. The existing reg_vcc3v3 is dropped as it is also available in the set of common regulators. Other unused regulators are disabled. Signed-off-by: Chen-Yu Tsai <wens@csie.org>
