Remove DVB-T2 BER as it does not work at all and I didn't find how to fix. Fix DVB-T and DVB-C BER. It seems to return new some realistic looking values. Use (1 << 24) base for CNR calculations to keep it in line with dvb logarithm functions. Move all statistic logic to mn88473_read_status() function. Use regmap_bulk_read() for reading multiple registers as a one go. Many more and less minor changes.
