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.
