In order to add configfs support, a usb function must be converted to use
the new interface. This patch converts the function to the new interface
and provides backward compatiblity layer, which can be removed after
all its users are converted to use the new interface.

Pull kconfig updates from Michal Marek:
"Yann E Morin was supposed to take over kconfig maintainership, but
this hasn't happened. So I'm sending a few kconfig patches that I
collected:
- Fix for missing va_end in kconfig
- merge_config.sh displays used if given too few arguments
- s/boolean/bool/ in Kconfig files for consistency, with the plan to
only support bool in the future"
* 'kconfig' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild:
kconfig: use va_end to match corresponding va_start
merge_config.sh: Display usage if given too few arguments

This patch adds support for the PLX USB3380 and USB3382.
This driver is based on the driver from the manufacturer.
Since USB338X is register compatible with NET2280, I thought that it
would be better to include this hardware into net2280 driver.
Manufacturer's driver only supported the USB33X, did not follow the
Kernel Style and contain some trivial errors. This patch has tried to
address this issues.
This patch has only been tested on USB338x hardware, but the merge has
been done trying to not affect the behaviour of NET2280.

The dependency on the isp1301 driver is not something that
should be in the main OHCI driver but rather the SoC specific
part of it.
This moves the dependency for LPC32xx into USB_OHCI_HCD_LPC32XX,
and changes the 'select ISP1301_OMAP' to a similar 'depends on'.
Since the same dependency exists for the client driver, do the
same change there.

Moves the s3c-hsotg driver into the dwc2 directory and uses the
dwc2 defines in hw.h. Renames s3c-hsotg.c to gadget.c.
NOTE: You can build both host and peripheral as a dynamically
linked module, but be aware that if you insmod dwc2_gadget, then
rmmod it, then insmod dwc2 and dwc2_platform for host mode, this
will not work. As the step to rmmod dwc2_gadget.ko will turn off
the clock to the USB IP. The dwc2 host driver currently does not
look to turn on a clock yet. A patch to fix that will be coming

Converting to configfs requires making the f_mass_storage.c a module.
But first we need to get rid of "#include "storage_common.c".
This patch makes storage_common.c a separately compiled file, which is
built as a utility module named u_ms.ko. After all mass storage users are
converted to the new function interface this module can be eliminated
by merging it with the mass storage function's module.
USB descriptors are exported so that they can be accessed from
f_mass_storage.
FSG_VENDOR_ID and FSG_PRODUCT_ID are moved to their only user.
Handling of CONFIG_USB_GADGET_DEBUG_FILES is moved to f_mass_storage.c.
The fsg_num_buffers static is moved to FSG_MODULE_PARAMETER users, so
instead of using a global variable the f_mass_storage introduces
fsg_num_buffers member in fsg_common (and fsg_config).
fsg_strings and fsg_stringtab are moved to f_mass_storage.c.
