Implicitly setting the tuner frequency each time the device is opened
seems no longer necessary, so it is removed. This speeds up opening the
device by about 120 ms.
It also avoids excessive firmware reloads because the default will load
the BASE and F8MHZ type firmwares independent of which device, video or
radio, is opened. Before this patch opening the radio device would
automatically trigger a BASE and F8MHZ firmware load only to immediately
replace them by the FM firmware.
