The scan logic will bypass the whole ->set_channel() logic from the top by calling the driver hook to just switch between channels when required. We can no longer rely on the "current" page/channel settings to set the right symbol duration. Let's add these as new parameters to allow providing the page/channel couple that we want. There is no functional change.
