After 62285963 (usb: musb: drop a gigantic amount of ifdeferry):

 - USB_GADGET_MUSB_HDRC is no longer selectable because it
   depends on the removed USB_MUSB_PERIPHERAL and USB_MUSB_OTG
   options

 - The Kconfig comment still says "Enable Host or Gadget support

now that we have the udc class, we can allow
multiple gadget controller drivers to be
compiled as modules. This will allow for
distro-like kernels for embedded devices.

With this patch, I managed to build an x86
kernel with support for many of the controllers
enabled:

CONFIG_USB_FUSB300=m
CONFIG_USB_R8A66597=m
CONFIG_USB_M66592=m
CONFIG_USB_AMD5536UDC=m
CONFIG_USB_CI13XXX_PCI=m
CONFIG_USB_NET2272=m
CONFIG_USB_NET2280=m
CONFIG_USB_GOKU=m
CONFIG_USB_LANGWELL=m
CONFIG_USB_EG20T=m

Also an ARM kernel with support for many controllers:

CONFIG_USB_FUSB300=m
CONFIG_USB_OMAP=m
CONFIG_USB_R8A66597=m
CONFIG_USB_GADGET_MUSB_HDRC=m
CONFIG_USB_M66592=m
CONFIG_USB_NET2272=m
CONFIG_USB_DUMMY_HCD=m

The next step would be to get rid of the
direct access to arch/ and mach/ directories
on some gadget controllers so that we can
build all of them without depending on their
respective ARCH_* symbols.

This patch adds SS support to the dummy hcd module.
It may be used to test SS device when no (SS) HW is
available.

USB 3.0 hub includes 2 hubs - one HS and one SS. This
patch adds support for a SS root hub in the dummy_hcd
module.

A new module parameter was added: is_super_speed. When
set to true, a SS root hub will also be registered and
the connected device will be enumerated over the SS
root hub. The default of this parameter is false.

This is based on the last release from PLX:
	http://www.plxtech.com/files/products/net2000/software/selectiontool/RE061204-net2272-linux2.6.18.tgz

I've managed to contact them and they've confirmed that this driver was
wholly written by PLX (Seth Levy).  While they have no problem with it
being merged (and they've already licensed it as GPL), they don't have
any interest in doing so themselves as this is an old part for them.

ADI has long had an add-on card which has this part on it, so we've been
keeping it up-to-date out of tree.  But now that PLX has confirmed the
source of the driver, we can can take the next step of cleaning it up and
getting it merged.

So here we are!  I've done quite a large clean up of the driver and
attempted to address all the common issues.  Hopefully in the process,
I haven't broken anything.  While it seems to still work with the board
that I have access to, it is not a PCI variant.  So I have not tested
any of the PCI logic myself (beyond clean compile).  Perhaps someone who
actually has a card and cares can do so.

I'll try to address further feedback, but don't expect miracles.  I'm
not really familiar with the part itself, just the platform glue.

This commit cleans the g_fs gadget hopefully making it more
readable.  This is achieved by usage of the usb_string_ids_tab()
function for batch string IDs registration as well as
generalising configuration so that a single routine is
used to add each configuration and bind interfaces.  As an
effect, the code is shorter and has fewer #ifdefs.

Moreover, in some circumstances previous code #defined
CONFIG_USB_FUNCTIONFS_GENERIC macro to prevent a situation
where gadget with no configurations is built.  This code removes
the #define form source code and achieves the same effect using
select in Kconfig.
