A register used to identify chip during probe was overwritten during
firmware download and due to that later probe's for warm chip were
failing. Detect chip from the another register, which is located on
different register bank 2.

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.
