The pxa2xx_udc.c driver is renamed to pxa25x_udc.c (the platform
driver name changes from pxa2xx-udc to pxa25x-udc) and the
platform driver name of pxa27x_udc.c is fixed to pxa27x-udc.
pxa_device_udc in devices.c is split into pxa25x and pxa27x flavors
and the pxa27x_device_udc is enabled in pxa27x.c.

The PXA25x and PXA27x USB device controller register definitions are
different.  Currently, they live side by side in pxa-regs.h, but only
one set is available depending on the setting of PXA25x or PXA27x.

This means that if we build to support both PXA25x and PXA27x, the
PXA27x definitions are unavailable, even to PXA27x specific code.

Remove these definitions from pxa-regs.h, and place them in separate
files.  Include these files where appropriate.

Note: according to the dependencies in drivers/usb/gadget/Kconfig,
we do not support the UDC on PXA27x nor PXA3xx CPUs, so remove the
platform devices from pxa27x.c and pxa3xx.c.

Various fixes to Atmel's high speed UDC driver.

  * Issue some missing disconnect() calls.  Currently they are only made
    when VBUS power goes away (on boards where the driver can sense such
    changes), but that's not enough for gadget drivers to clean out all
    the state that's needed.  Missing calls were:

      - After USB reset, before starting enumeration.
      - When unregistering a gadget driver, before unbind().

  * Don't assume gadget drivers provide disconnect callbacks; make sure
    to not call through a null pointer!

  * When the driver doesn't provide an unbind() callback, refuse to
    unregister it.

Also remove two bogus "error" messages:

  * Related to mis-handling of disconnect() ... don't emit error messages
    for disconnect() handlers that disable endpoints.  All of them should
    be doing that; the problem is (unfixed) oddness in atmel_usba_udc.

  * Don't emit a diagnostic for a curious and transient nonfatal error
    that shows up sometimes with EP0.

Those messages spammed syslog, for no good reason.

Microchip has changed the PICDEM FS USB demo device (0x04d8:000c)
to use bulk transfer and not interrupt transfer. So I've updated the libusb
based program here (Post #31).
	http://forum.microchip.com/tm.aspx?m=106426&mpage=2

So I believe that the in-kernel ldusb driver will no longer work with the
demo firmware.  It should be removed.

Enables the SD-Card interface on the GI 0401 HSUPA card from Option.

The unusual_devs.h entry is necessary because the device descriptor is
vendor-specific. That prevents usb-storage from binding to it as an
interface driver.

This revised patch adds a small comment explaining why and reduces the

   just use the high bits for a driver revision code.

 - Serial numbers that aren't specific to individual devices
   are useless; stop reporting "0" for this.

 - Since it's not part of a CDC-conformant function, the "bulk only"
   configuration shouldn't be using "CDC Data" as its interface class.

This removes a needless data structure from the serial gadget code;
it's a small code shrink, and a larger data shrink.

Since "struct usb_request" already has a "struct list_head" reserved
for use by gadget drivers, the serial gadget code doesn't need to
allocate wrapper structs to hold that list ... it can (and should!)
just use the list_head provided for that exact use.

Some cleanup/reorg of g_serial ... simplifying it, and disentangling
its structure so morphing it into a "function" driver (combinable with
other interfaces) should be less painful.

 - Remove most forward declarations
     * put tty and gadget driver structs after their contents
     * snug module init/exit decls next to their functions
     * reordered some functions

 - Other cleanup:
     * convert a funky macro to an inline function
     * snug up module params next to their declarations
     * add missing driver.owner
     * add separator lines between major driver sections

 - Add comments re potential parameter/#define changes:
     * only supports one port (shrank GS_NUM_PORTS)
     * changing from 9600-8-N-1 affects multiple sites

 - Remove net2280-specific optimization ... it was being done
   way too late, can be done by net2280 module options, and in
   any case doesn't matter at any sane serial data rates.

There are no behavioral changes, but the macro thing saves I-space.

After some time (ca. 5min) or if virtual CD is ejected, device id
changes to 1410:4400:

Unfortunately there are a few attributes which cannot be created that
early.  The "descriptors" attribute is binary and so must be created
separately.  The power-management attributes can't be created until
the dev/power/ group exists.  And the interface string can vary from
