Well, in all fairness, that _is_ what "platform_data" is supposed to be. A platform-specific pointer to whatever data structure that platform needs to have to do the device ops. Platforms that don't need the function pointers wouldn't have any function pointers there, while others would have not just the function pointers, but could have some other bus-dependent data too.
(And this is what at least HP-PA does, as does ARM...)
So it's definitely not unsuitable for this. It does seem like USB jumped the gun a bit, though.
