Input: synaptics - ensure we reset the device on resume

When resuming from suspend newer Synaptics touchpads do not recover
correctly.  Analysis of the resume sequence as applied in Linux was
compared to that of other operating systems.  This indicated that the
other OSs were resetting the mouse before attempting to detect it (for
all Synaptics touchpads, old and new).  Applying this same modification
fixes these newer Synaptics touchpads and brings the driver into line
with common OS reset behaviour.
