Fix HID descriptor for Surface Laptops

Browse source

The HID descriptor on the Surface Laptops defines the contact count
incorrectly, causing Linux to read a contact count of zero and thus not
producing any touch events. The HID descriptor claims that the contact
count is reported 4 times as one byte value, whereas it is only reported
one time but followed by 3 padding bytes.
