Input: goodix - restore config on resume if necessary

Some devices, e.g the Trekstor Primetab S11B, lose there config over
a suspend/resume cycle (likely the controller loses power during suspend).

This commit reads back the config version on resume and if matches the
expected config version it resets the controller and resends the config
we read back and saved at probe time.
