[media] qt1010: remove fake implementaion of get_bandwidth()
This driver implements a fake get_bandwidth() callback. In reallity, the tuner driver won't adjust its low-pass filter based on a bandwidth, and were just providing a fake method for demods to read whatever was "set". This code is useless, as none of the drivers that use this tuner seems to require a get_bandwidth() callback. While here, convert set_params to use the DVBv5 way to pass parameters to tuners.
