[PATCH] Prof 7301: switching frontend to stv090x, fixing "LOCK FAILED" issue

[Mariusz Bialonczyk <manio@skyboo.net>]

Fixing the very annoying tunning issue. When switching from DVB-S2 to DVB-S,
it often took minutes to have a lock.
This issue is known to Igor M. Liplianin and was also reported ie. in the
following posts:
http://article.gmane.org/gmane.linux.drivers.video-input-infrastructure/24573
http://article.gmane.org/gmane.linux.drivers.video-input-infrastructure/25275

The patch is changing the frontend from stv0900 to stv090x.
The card now works much more reliable. There is no problem with switching
from DVB-S2 to DVB-S, tunning works flawless.
