When using OF defined controllers the platform data struct is shared between all devices, so it can't be used for device specific settings. However it is currently used for the OF properties needs-reset-on-resume and has-transaction-translator. To fix this issue move setting hcd->has_tt to the probe and move pdata->reset_on_resume to the private data.
