This solves a bug with the wireless receiver:
- at plug, the wireless receiver does not know which Wacom device it is
connected to, so it does not actually creates all the LEDs
- when the tablet connects, wacom->wacom_wac.features.type is set to the
proper device so that wacom_wac can understand the packets
- when the receiver is unplugged, it detects that a LED should have been
created (based on wacom->wacom_wac.features.type) and tries to remove
it: crash when removing the sysfs group.
Side effect, we can now safely call several times wacom_destroy_leds().

All USB Wacom tablets are actually HID devices.
For historical reasons, they are handled as plain USB devices.
The current code makes more and more reference to the HID subsystem
like implementing its own HID report descriptor parser to handle new
devices.
From the user point of view, we can transparently switch from this state
to a driver handled in the HID subsystem and clean up a lot of USB specific
code in the wacom.ko driver.
The other benefit once the USB dependecies have been removed is that we can
use a tool like uhid to make regression tests and allow further cleanup or
new implementations without risking breaking current behaviors.
To match the current handling of devices in wacom_wac.c, we rely on the
hid_type set by usbhid. usbhid sets the hid_type to HID_TYPE_USBMOUSE when
it sees a USB boot mouse protocol declared and HID_TYPE_USBNONE when the
device is plain HID. There is thus a one to one matching between the list
of supported devices before and after the switch from USB to HID.

0xA1, 0x01, /* Collection (Application), */

Reading the partial HID Descriptor is causing a firmware lockup in some
sensor hubs. Instead of a partial read, this patch implements the
i2c hid fetch using a fixed descriptor size (30 bytes) followed by a
verification of the BCDVersion (V01.00), and value stored in
wHIDDescLength (30 Bytes) for V1.00 descriptors.
As per i2c hid spec, this is the preferred model.
From hid-over-i2c-protocol-spec-v1-0:
There are a variety of ways a HOST may choose to retrieve
the HID Descriptor from the DEVICE. The following is a preferred
implementation but should not be considered the only implementation.
A HOST may read the entire HID Descriptor in a single read by
issuing a read for 30 Bytes to get the entire HID Descriptor
from the DEVICE.However, the HOST is responsible for validating that
1. The BCDVersion is V01.00 (later revisions may have different
descriptor lengths), and
2. The value stored in wHIDDescLength is 30 (Bytes) for V1.00
descriptors.
