The previous implementation of eGalax protocol was not satisfying as
we had to manually set x/y ranges as they were corrupted after reading
the report descriptor.
Indeed, the report descriptor provided a stylus input interface which
override the correct values.

This patch omits this input, thus leaving the correct value untouched,
and the MT_QUIRK_EGALAX_XYZ_FIXUP not required anymore.

This reverts commit 0db3bfc7 (""HID: multitouch: decide if hid-multitouch
needs to handle mt devices").

The generic detection of hid-mt devices has two major flaws, and was
merged prematurely. Firstly, the hid-multitouch gets loaded even when
the device is handled by a special device. Secondly, the patch only
partially duplicates the device whitelist already present in hid-core,
effectively rendering a number of devices non-functional.

Now that hid-generic ignores all win7 compatible multitouch devices, this patch
allows hid-multitouch to catch them.  The idea is to rely on the quirk

This change fixes two problems.

First, it ensures that the hid-multitouch driver does not incorrectly
map GenericDesktop usages that are intended for other applications,
such as a Mouse.

Second, it sets the appropriate input properties so that user-space
can distinguish TouchScreen devices (INPUT_PROP_DIRECT) from
TouchPad devices (INPUT_PROP_POINTER) and configure them accordingly.

Since the inclusion of eGalax devices in 2.6.39, I've got some
bug reports for 480d and other devices.
The problem lies in the reports descriptors: eGalax supports both
pen and fingers, and so the reports descriptors contained both.
But hid-multitouch relies on them to detect the last item in each
field to send the multitouch events. In 480d, the last item is not
Y as it should but Pressure. That means that the fields are not
aligned and X,Y are at 0,0 (the other touch coordinates of the report).

With this patch, the detection is made only when the field ContactID
has been detected inside the collection.

There is still a problem with the detections of the range as stylus
and fingers may not have the same min/max, but it's a start.

the current implementation requires the devices to report
HID_DG_CONTACTCOUNT to set the last_field_index value.
However, devices reporting in serial mode (DWAV and PenMount)
do not send this field.
Other devices (3M) add other fields in the reports descriptor
that are not multitouch related at the end, thus the need to
add a special case in the default case when handling events.

A first work around has been set up but with PenMount devices,
we have reached the limit.

The idea is to calculate the last_field_index by relying only on
multitouch fields the device send. This allows us to remove
the handling of non-multitouch events in hid-multitouch, and
guarantee that the function mt_emit_event is always called.

This patch merges the hid-3m-pct driver into hid-multitouch.
To keep devices working the same way they used to with hid-3m-pct,
we need to add two signal/noise ratios for width and height.
We also need to work on width/height to send proper

Importing 3M into hid-multitouch also solved the bug in which
devices handling width and height in their report descriptors
did not show ABS_MT_TOUCH_MAJOR and ABS_MT_TOUCH_MINOR.
