Input: synaptics - refactor agm packet parsing
When a Synaptics touchpad is in "AGM" mode, and multiple fingers are
detected, the touchpad sends alternating "Advanced Gesture Mode" (AGM) and
"Simple Gesture Mode" (SGM) packets.
The AGM packets have w=2, and contain reduced resolution finger data.
The SGM packets have w={0,1} and contain full resolution finger data.
Refactor the parsing of agm packets to its own function, and rename the
synaptics_data.mt field to .agm to indicate that it contains the contents of
the last agm packet.
