Input: psmouse - reset all types of mice before reconnecting

Synaptics hardware requires resetting device after suspend to ram
in order for the device to be operational. The reset lives in
synaptics-specific reconnect handler, but it is not being invoked
if synaptics support is disabled and the device is handled as a
standard PS/2 device (bare or IntelliMouse protocol).

Let's add reset into generic reconnect handler as well.
