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.

812c) Probing the cards with broken PCI subsystem ID
82--------------------------------------------------
83There are some TwinHan cards that the EEPROM has become corrupted for some
84reason. The cards do not have correct PCI subsystem ID. But we can force
85probing the cards with broken PCI subsystem ID
