add dtv78 parameter
The dtv78 entry is a hack meant for card usage in Australia, that
speeds up channel detection there. Again, it should be specified
only when needed, and at per-board basis.
I have test and auto detect doesn't work right. That is also region
specific staff and it's better to set outside. In other words in Germany
it must set this param and in other country, which use only 7MHz or 8MHz it doesn't set (i.e. Australia).
xc3028 has a logic to detect and work on both Australia and Europe.
If that logic is broken, we should fix it, not adding a manual
parameter for it.
It positively a bug. When I use lower band (7MHz, load DTV7 SCODE) it
doesn't work, then I go in the high band (8MHz, load DTV78, DTV8 SCODE)
and have channels and can watch TV. If I go now in the lower band (7MHz,
don't reload SCODE) it works. This effect is for me a bug.
