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.
