V4L/DVB (4497): Reset USB part of DViCO Dual Digital during PCI driver attach

Browse source 
If the FX2 does not reset properly during reboot, it can present an
invalid USB device ID and fail to attach.  Prevent this situation
from occuring by resetting the USB part of the card when the PCI part
probes.
Also fix the GPIO configurations so that analog capture will not
inadvertantly reset the USB part.
