V4L/DVB (3406): Use refactored LNBP21 and BSBE1 code
Use refactored LNBP21/BSBE1 code for Technotrend/Hauppauge DVB-S rev 2.3. As a side effect, FE_ENABLE_HIGH_LNB_VOLTAGE ioctl is supported now. Signed-off-by: Oliver Endriss <o.endriss@gmx.de> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
