[PATCH synaptics] Recognise the soft button area property is before clickpad is enabled

[Peter Hutterer]

Otherwise the driver has no internal reference to the soft button area
property and will ignore any setting.

Also, if a client sets this property, we claim it as our own and disallow
deletion.
