V4L/DVB (6656): zl10353: store frequencies in 0.1kHz to eliminate rounding errors
Whilst reanalysing my formulas I realised it was no longer possible to get the right values for a 36.1667MHz IF due to rounding problems. Storing frequencies in units of 0.1kHz makes it possible to calculate these again correctly.
