[U-Boot] U-Boot 2018.07 Still Broken for Allwinner H3 SoCs

[Chen-Yu Tsai]

This is on a Libre Computer ALL-H3-CC H3 variant. Still running a
bisect, but v2018.07-rc1 is a working version. From the EHCI error
messages, I'm thinking it might be related to the USB changes lately.
Not sure if any other SoCs (ex. A64) are broken or not at the moment.
