libpayload: Make OHCI enums into types

The OHCI header file declares various enums as follows:

    enum { ... } enum_name;

Since the name is at the end, this is actually declaring a variable
called enum_name and *not* a type, which is causing a multiple
definition error in GCC 10. Move the enum_name before the opening brace
to prevent this.
