module_param(bool) used to counter-intuitively take an int. In
fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy
trick.
It's time to remove the int/unsigned int option. For this version
it'll simply give a warning, but it'll break next kernel version.

This commit renames the “speed” field of the usb_gadget_driver
structure to “max_speed”. This is so that to make it more
apparent that the field represents the maximum speed gadget
driver can support.
This also make the field look more like fields with the same
name in usb_gadget and usb_composite_driver structures. All
of those represent the *maximal* speed given entity supports.
After this commit, there are the following fields in various
structures:
* usb_gadget::speed - the current connection speed,
* usb_gadget::max_speed - maximal speed UDC supports,
* usb_gadget_driver::max_speed - maximal speed gadget driver
supports, and
* usb_composite_driver::max_speed - maximal speed composite
gadget supports.

peripheral drivers are using usb_add_gadget()/usb_del_gadget() to
register/unregister to the udc-core.
The udc-core will take the first available gadget driver and attach
function driver which is calling usb_gadget_register_driver(). This is
the same behaviour we have right now.
Only dummy_hcd was tested, the others were compiled tested.

There was an unlock missing on the error path.
Also I did a small cleanup by changing ep->dev->lock for just dev->lock.
They're the same lock, but dev->lock is shorter and that's how it is
used for the spin_unlock_irqrestore() call.

This PCH_UDC driver does not work normally when "Ethernet gadget" is used.
This patch fixed this issue.
The following was modified.
- The FIFO flush process.
- The descriptor creation process.
- The adjustment of DMA buffer align.
Currently the PCH_UDC driver can work normally with "Ethernet gadget",
"Serial gadget" or "File-backed Storage Gadget".

This patch fixes an issue where the driver does not handle out data in
setup transactions.
The per endpoint cached status register is cleared in the
pch_udc_svc_control_out function. When there is out data available the
function pch_udc_svc_data_out is called which tries to pick it up the
status, which now is cleared to 0. When the status is 0, the function
doesn't start reading the data from the FIFO.
There is a second bug in all this, pch_udc_svc_data_out takes the
endpoint number (0 for EP0), while pch_udc_svc_control_out passes the
endpoint index (1 for EP0). Effectively pch_udc_svc_data_out picks up
the wrong internal ep structure.
This patch makes sure to put back the cached status and pass the
endpoint number rather than index when calling pch_udc_svc_data_out.

This patch adds the USB device driver of EG20T(Topcliff) PCH.
EG20T PCH is the platform controller hub that is going to be used in
Intel's upcoming general embedded platform. All IO peripherals in
EG20T PCH are actually devices sitting on AMBA bus.
EG20T PCH has USB device I/F. Using this I/F, it is able to access system
devices connected to USB device.
