V4L/DVB (3378): Restore power on defaults of tda9887 after tda8290 probe

Browse Source 
The probing code for tda8290 changes the state of the tda9887 GP ports.
The patch assumes that if probing for tda8290 failed, this must be a 
tda9887 and restores its power on defaults.
This should solve the module load order issue with some pinnacle cards.
