V4L/DVB (11236): tda827x: fix locking issues with DVB-C
Separate tuning table for DVB-C solves tuning problem at 388MHz
TechnoTrend C-1501 DVB-C card does not lock on 388MHz. I assume that
existing frequency table is valid for DVB-T.
This is suggested by the name of the table: tda827xa_dvbt.
Added a table for DVB-C with the name tda827xa_dvbc.
Added runtime selection of the DVB-C table when the tuner is type
FE_QAM.
This should leave the behaviour of this driver with with DVB_T tuners
unchanged. This modification is in file tda827x.c
The tda827x.c gives the following warning message when debug=1:
tda827x: tda827x_config not defined, cannot set LNA gain!
Solved this by adding a tda827x_config struct in budget-ci.c.
