ARM: sun8i: a83t: Add USB PHY and host device nodes
The A83T has 3 USB PHYs, 1 for USB OTG, 1 for standard USB 2.0, 1 for USB HSIC. EHCI0/OHCI0 are the standard USB host pair, while EHCI1 is the host controller for HSIC. OTG is not added yet. Signed-off-by: Chen-Yu Tsai <wens@csie.org> Tested-by: Maxime Ripard <maxime.ripard@free-electrons.com>
