[PATCH] usb: ohci-da8xx: remove unused platform data

[Bartosz Golaszewski]

From: Bartosz Golaszewski <bartosz.golaszewski@xxxxxxxxxx>

We no longer support any board files for DaVinci in mainline and so
struct da8xx_ohci_root_hub is no longer used. Remove it together with
all the code it's used for.
