Add support for OS descriptors. The new format of descriptors is used,
because the "flags" field is required for extensions. os_count gives
the number of OSDesc[] elements.
The format of descriptors is given in include/uapi/linux/usb/functionfs.h.

For extended properties descriptor the usb_ext_prop_desc structure covers
only a part of a descriptor, because the wPropertyNameLength is unknown
up front.

ffs_do_desc() handles one descriptor, while ffs_do_descs() handles a number
of descriptors. The tho names are so similar that it causes confusion.
Rename to reflect their purpose better.

commit c63d2225 ("usb: gadget: pxa25x_udc: use devm_ functions")
introduced the use of devm_gpio_request in this driver, but did not
correctly include the header file declaring this function, which
causes a build failure.

This changes pxa25x_udc to include linux/gpio.h instead of asm/gpio.h
to fix this.

Syscall mount returns -ENODEV error if requested FS type
has not been found. Returning the same error from FFS mount
callback makes value returned to userspace misleading.

Other file systems returns -ENOENT if requested device
has not been found. Adjust FFS to this convention to make
error codes meaningfull.

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.

This patch moves data allocated using kzalloc to managed data allocated
using devm_kzalloc and cleans now unnecessary kfrees in probe and remove
functions. Also, the unnecesary labels are removed and some labels are
renamed to preserve ordering.

The following Coccinelle semantic patch was used for making the change:

@platform@

struct platform_driver p = {
  .probe = probefn,
  .remove = removefn,
};
