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.

Implement DVBv5 statistics support for DVB-T, DVB-T2 and DVB-C. All
information was taken from the LinuxTV wiki, where Benjamin Larsson has
documented all registers:

Finalize the driver.
It still lacks a lot of features, like all statistics and PLP
filtering, but basic functionality and sensitivity is pretty good
shape.
