V4L/DVB (3568j): adv7175: Drop unused encoder dump command

Drop support for the ENCODER_DUMP command in the adv7175 driver.  ENCODER_DUMP
was never actually defined as far as I can see, so the code was ifdef'd out,
and I suspect it was never used, not even once, as it includes an obvious
array overrun.

The register values of this specific chip can be dumped in a generic way using
the i2c-dev driver and the "i2cdump" user-space tool if it is ever really
needed.
