HID: quirk for MS Wireless Desktop Receiver (model 1028) 

Microsoft's wireless desktop receiver (Model 1028) has a bug in the report
descriptor -- namely, in four seperate places it uses USAGE_MIN and _MAX when
it quite obviously doesn't intend to.

In other words, it reports that it has pretty much _everything_ in 'consumer'
and 'generic desktop'.  And then the X evdev driver believes I have a mouse
with 36 absolute axes and a huge pile of keys and buttons, when I in fact,
should have zero.  255/256 in three of the cases, and 0-1024 in another.

This patch fixes the report descriptor of this device before it enters the HID
parser.
