[PATCH] input/mouse/synaptics: Add SYN1217 to PNP detection list

[Paul Menzel]

Date: Wed, 14 Feb 2018 18:16:43 +0100

On the TUXEDO Book BU1406, since Linux 4.12, the Linux kernel logs the 
message
below.

```
kernel: psmouse serio1: synaptics: Your touchpad (PNP: SYN1217 PNP0f13) 
says it can support a different bus. If i2c-hid and hid-rmi are not 
used, you might want to try setting psmouse.synaptics_intertouch to 1 
and report this to linux-input@xxxxxxxxxxxxxxxx
```

Booting with `psmouse.synaptics_intertouch=1`, the touchpad continues to
work, so add the ID of the device to the list of IDs, whose devices
support I2C mode.
