[PATCH v3 19/19] usb: ohci-at91: Add `ohci_t` field in `ohci_at91_priv`

[Sergiu Moga]

From: Cristian Birsan <cristian.birsan at 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.
