viafb: reduce viafb_set_iga_path usage
The result of viafb_set_iga_path can change after init only in the hotplug ioctl. So we can move it there rather than doing it always when a new mode is set. The setup during init is done via a call from the init chip funtion. This change enables a stable mapping between the old device scheme and a new more powerfull one.
