By comparing the traffic between Pixelview (cx23102-based and Kworld
(saa7134-based), the only difference is at register 0xd5. After some
tests, It seems that it is used to change mode between serial and parallel.

This adds the trivial bits to mb86a20s. As the driver won't touch
at the channel/layer parameters, this may not be enough for
receiving all channels, especially ISDB-Tsb, but the driver worked
properly for receiving video channels on my tests.

On our tests with Leadership ISDBT, the s921 frontend were not work. As its
design contained some weird things, it ended to be easier to just re-write
it, getting another frontend as an example (cx24123).

As the old s921 driver weren't used, there's no regression. Some info from
the old frontend were used as a way to double check the behavior that were
noticed on the USB dumps retrieved from Leadership driver.
