[media] msi3101: changes for tuner PLL freq limits

I made some tuner freq limit tests against RF signal generator.
Adjust some PLL limits according to these test results.
Here are the results, taken from two different devices.
Ranges are measured RF limits + calculated VCO limits.
Mirics MSi3101 SDR Dongle:
VHF_MODE  52 - 132  1664 - 4224
B3_MODE  103 - 263  1648 - 4208
B45_MODE 413 - 960  1652 - 3840
Hauppauge WinTV 133559 LF:
VHF_MODE  49 - 130  1568 - 4160
B3_MODE   98 - 259  1568 - 4144
B45_MODE 391 - 960  1564 - 3840
