Instead of global variables, use the extra_priv_size of
the ohci driver.
We cannot yet move the ocic mask because this is used on
the interrupt handler which is registerded through platform
data and does not have an hcd pointer. This will be moved
on a later patch.

This adds the ohci device node for the da850 soc.
It also enables it for the omapl138 hawk board.

To make it easier to review. I will split the arch/arm and driver
patches into separate series.

The usb driver can now take a regulator instead of the platform
callbacks for vbus handling. Lets use a regulator so we can remove
the callbacks in a later patch.

The hawk board VBUS is fixed to a 5v source, and the over
current pin is actually not connected to the SoC.
Do not reseve these gpios for OHCI as they are not related
to usb.

Now that all ohci users are are using a regulator, we can
remove the platform callbacks and data.
potpgt is no longer necessary as a power on delay time can
be specified for the regulator itself.

Now that the platform callback is removed, we can move the over
current indictor changed flag to the private data structure.
Since the driver only handles a single port, there is no need
for ocic to be a mask, we can use a simple flag instead.

* rebased on top of regulator-next
Changes v1->v2
* add new API to get error status instead of extending events (Mark)
* use gpiod for fixed regulator: This spears us extra platform
data and bindings
