Instead of repeating duplicate parameters to each delivery system,
just add a section for each specific delivery system, showing
what's applicable to each case. This helps userspace app developers
to know what DVB parameters are applicable to each delivery system.

The old way of setting delivery system parameters were to use
an union with specific per-system parameters. However, as newer
delivery systems required more data, the structure size weren't
enough to fit. So, recomend using the DVBS2API instead.

There were lots of DVB S2API parameters that were never documented.
Let's add a definition for all of them, based on what's currently
used inside the core and the drivers.

This patch causes the tuner reset command to be ignored in the firmware
code, since this only happens when the BASE/INIT1 firmware is loaded by
