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. Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
