33d2832ab0 USB: gadget: Make g_hid device class conform to spec.
HID devices should specify this in their interface descriptors, not in the
device descriptor. This fixes a "missing hardware id" bug under Windows 7 with
a VIA VL800 (3.0) controller.

35a0e0bf6f usb: gadget: add max_speed to usb_composite_driver
This field is used by the Gadget drivers to specify
the maximum speed they support, meaning: the maximum
speed they can provide descriptors for.

The driver speed will be set in consideration of this
value.

c9bfff9c98 usb gadget: don't save bind callback in struct usb_configuration
The bind function is most of the time only called at init time so there
is no need to save a pointer to it in the configuration structure.

This fixes many section mismatches reported by modpost.

89ba85d401 USB: gadget: section mismatch warning fixed
In may gadgets bind and bind like functions were in a init section
as they were only run during initialisation.  However, being
callback functions they were referenced from structures in “normal”
sections.  Changing the tag from “__init” to “__ref” fixes the
warnings.

71adf11894 USB: gadget: add HID gadget driver
g_hid is a USB gadget driver implementing the Human Interface Device class
specification. The driver handles basic HID protocol handling in the
kernel, and allows userspace to read/write HID reports trough /dev/hidgX
character devices.
