[PATCH 14/19] [media] dvb-frontends/cxd2841er: more configurable TSBITS

[Daniel Scheller <d.scheller.oss@gmail.com>]

From: Daniel Scheller <d.scheller@gmx.net>

Bits 3 and 4 of the TSCONFIG register are important for certain hardware
constellations, in that they need to be zeroed. Add a configuration flag
to toggle this.
