Subject: [media] tda10071: force modulation to QPSK on DVB-S

commit db4175ae2095634dbecd4c847da439f9c83e1b3b upstream.

Only supported modulation for DVB-S is QPSK. Modulation parameter
contains invalid value for DVB-S on some cases, which leads driver
refusing tuning attempt. Due to that, hard code modulation to QPSK
in case of DVB-S.
