Subject: [PATCH 1/3] Input: synaptics - report clickpad property

With the new input property interface, it is possible to report the
special quirks of a device using ioctl/sysfs. This patch sets up the
device as a pointer, and reports the clickpad functionality via the
INPUT_PROP_BUTTONPAD property.
