This adds a USB driver using the generic platform device driver for the
USB controller found on the Broadcom ssb bus. The ssb bus just
exposes one device which serves the OHCI and the EHCI controller at the
same time. This driver probes for this USB controller and creates and
registers two new platform devices which will be probed by the new
generic platform device driver. This makes it possible to use the EHCI
and the OCHI controller on the ssb bus at the same time.

The old ssb OHCI USB driver will be removed in the next step as this
driver also provide an OHCI driver and an EHCI for the cores supporting
it.

Fix abuse of interface data which was used to signal device disconnect.

Use the usb_serial disconnect flag and mutex where appropriate.

Note that there's no need to grab the mutex in chase_port as it does not

This function is never called now. Because we don`t send much data
to the device, only one byte via usb_interrupt_msg(). That doesn't require
callback function. But without declaration of write_int_callback inside
the struct usb_serial_driver, the usb_serial_probe doesn't initialize
endpoint address for the interrupt out pipe(interrupt_out_endpointAddress).
This endpoint is necessary for sending data via usb_interrupt_msg()
function.

Many users of debugfs copy the implementation of default_open() when
they want to support a custom read/write function op.  This leads to a
proliferation of the default_open() implementation across the entire
tree.

Now that the common implementation has been consolidated into libfs we
can replace all the users of this function with simple_open().

This replacement was done with the following semantic patch:

<smpl>
@ open @
identifier open_f != simple_open;
identifier i, f;
@@
-int open_f(struct inode *i, struct file *f)
-{
(
-if (i->i_private)
-f->private_data = i->i_private;

-f->private_data = i->i_private;
)
-return 0;
-}

@ has_open depends on open @
identifier fops;
identifier open.open_f;
@@
struct file_operations fops = {
...
-.open = open_f,
+.open = simple_open,
...
};
</smpl>

The DT information are filled in a pdata structure and then passed on
to the usual check code of the probe function. Thus we do not need to
redo the gpio checking and irq configuration in the DT-related code.
On the other hand, we setup GPIO direction in driver for vbus and
overcurrent. It will be useful when moving to pinctrl subsystem.
