From: Daniel Scheller <d.scheller@xxxxxxx>
Allow for tuning to transponders with specific modulations in
set_parameters(). Setting a specific modulation will also enable lower
modulations.
Picked up from the upstream dddvb GIT. Upstream also has support for
APSK64/128/256 modulations which aren't supported yet by the DVB
API, so comment them out until support for them is added.
