arm64/sunxi: A64-Olinuxino - No USB

[Philip Rinn]

Hi list,

USB is not working on my Olimex A64-Olinuxino-1Ge4GW Rev. D. It seems, the
regulators are not correctly set up in the dt:

I get a lot of

sun4i-usb-phy 1c19400.phy: Couldn't get regulator usb0_vbus... Deferring probe

Attaching a USB key results in:

[ 5.158016] usb 4-1: new low-speed USB device number 2 using ohci-platform
[ 5.350010] usb 4-1: device descriptor read/64, error -62

I attached the full dmesg.

[As USB isn't working in u-boot either, I also attached the u-boot messages. I
already posted on the u-boot mailing list:
