[PATCH] hid-microsoft: Add ID's for Surface Type/Touch Cover 2

[Reyad Attiyat <reyad.attiyat@gmail.com>]

This patch fixes bug 64811 (https://bugzilla.kernel.org/show_bug.cgi?id=64811)
The Microsoft Surface Type/Touch cover 2 devices have the flag HID_DG_CONTACTID in their reports.This causes the device to bind to the hid-multitouch driver, which doesn't handle generic keyboard/mouse input events.
The patch adds the hardware id's of the device to hid-microsoft and to the HID special driver array, which makes the device get handled by hid-generic/hid-input properly.
