V4L/DVB (7077): bt878: remove handcrafted PCI subsystem ID check
This patch moves the subsystem ID and subsystem vendor ID check from probing function to the PCI generic function by describing subsystem IDs in pci_device_id table. This enables to add new PCI IDs to a device driver pci_ids table at runtime by new_id file in sysfs pci driver tree.

+2c) Probing the cards with broken PCI subsystem ID
+--------------------------------------------------
+There are some TwinHan cards that the EEPROM has become corrupted for some
+reason. The cards do not have correct PCI subsystem ID. But we can force
+probing the cards with broken PCI subsystem ID
