V4L/DVB (7186): tda10086: make the 22kHz tone for DISEQC a config option
Some cards need the diseqc signal modulated, while some just need the envelope to control the LNB supply. This fixes Bug 9887 Signed-off-by: Hartmut Hackmann <hartmut.hackmann@t-online.de> Acked-by: Oliver Endriss <o.endriss@gmx.de> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
