DVB: cx23885: DVB Transport cards using DVB port VIDB/TS1 did not stream
(cherry picked from commit 52ce27bfc4d302a3e28267a5820a8b031ceccee9)
DVB: cx23885: DVB Transport cards using DVB port VIDB/TS1 did not stream
Certain DVB cards that have demodulators on TS1/VIDB were not
streaming packets.
This ensure the pin directions on PAD_CTRL are set correctly,
solving the issue.
