Enable the second USB controller, which is connected to a hub with 4
ports. The first controller is for the OTG port and is currently not
supported.

Hi Neil,

I noticed this change to the bus width configuration isn't actually
needed. The USB port works with or without it. The kernel driver
doesn't set 16bit mode, so can you please remove these 4 lines from
the commit before sending the pull request?

Thanks,
Beniamino
