[media] radio-gemtek-pci: remove duplicate driver
The radio-gemtek-pci driver is for the same hardware as the radio-maxiradio driver which uses the same GemTek PR103 and tea5757 combination and the two drivers are identical. I chose the maxiradio over the gemtek-pci driver since the maxiradio has support for mono/stereo detection. Tested with my gemtek-pci card.
