From: Cristian Birsan cristian.birsan@microchip.com
The `ohci_register` function expects that the OHCI driver's priv is a struct whose first field is of type `ohci_t`. The original conversion to DM did not have it and this inconsistency revealed itself whenever U-Boot required multiple memory allocations resulting in a memory overwrite of where this field would supposedly be.
Thus, add this missing field and automatically increase the implicit size of the driver's priv to avoid whatever future memory allocations may take place from overwriting it.
