      mb86a20s: Add a few more register settings at the init seq · ebe96749
      Mauro Carvalho Chehab authored
      Some time ago, Manoel sent us a patch adding more stuff
      to the init sequence. However, his patch were also doing
      non-related stuff, by changing the init logic without
      any good reason. So, it was asked for him to submit a
      patch with just the data that has changed, in order to
      allow us to better analyze it.
      
      As he didn't what it was requested, I finally found some
      time to dig into his init sequence and add it here.
      
      Basically, new stuff is added there. There are a few changes:
      
      1) The removal of the extra (duplicated) logic that puts
         the chip into the serial mode;
      2) Some Viterbi VBER measurement init data was changed from
         0x00 to 0xff for layer A, to match what was done for
         layers B and C.
      
      None of those caused any regressions and both make sense
      on my eyes.
      
      The other parameters additions actually increased the
      tuning quality for some channels. Yet, some channels that
      were previously discovered with scan disappered, while
      others appeared instead. This were tested in Brasilia,
      with an external antena.
      
      At the overall, it is now a little better. So, better to
      add these, and then try to figure out a configuration that
      would get even better scanning results.
