The calc_regs() callback is used by a few frontends (mt352, nxt200x,
digitv and zl10353). On all places it is called, the parameters are
set by DVBv5 way. So, just use the DVBv5 struct and remove the
extra parameter.

SYS_DVBC_ANNEX_AC is an alias for SYS_DVBC_ANNEX_A. However,
the first one is incorrect, as not all devices support both.
So, replace its occurrences by the proper value (either
SYS_DVBC_ANNEX_A or both SYS_DVBC_ANNEX_A and SYS_DVBC_ANNEX_C).

Rewrite whole af9013 demod driver in order to decrease I2C I/O.

While tda10021 supports both DVB-C Annex A and C, it is currently
hard-coded to Annex A. Add support for Annex C and re-work the
code in order to report the delivery systems, thans to Andreas,

Instead of using a roll-off factor, change DRX-K & friends to select
the bandwidth filter and the Nyquist half roll-off via delivery system.

This provides a cleaner support for Annex A/C switch.

The DRX-K doesn't change the delivery system at set_properties,
but do it at frontend init. This causes problems on programs like
w_scan that, by default, opens both frontends.

Instead, explicitly set the format when set_parameters callback is
called.
