bt878: remove handcrafted PCI subsystem ID check
From: Akinobu Mita <akinobu.mita@gmail.com>
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.
