When running my 8M Plus in Host mode, I got similar "Failed to get
PHY0 for usb" failures, but I hadn't yet bisected it. The PHY itself
doesn't appear to have a clock reference itself, but it does reference
a power-domain which uses multiple clocks. I wonder if one of the
clocks in the hsio power domain isn't registering properly. I won't
be near my 8MP until much later tonight, but can you run 'dm tree' to
see what clocks are enumerated and which might be missing?
