The PTT device can only support the devices on the same PCIe core,
within BDF range [lower_bdf, upper_bdf]. It's not correct to assume
the devices on the root bus are from the same PCIe core, there are
cases that root ports from different PCIe core are sharing the same
bus. So check when initializing the filters list.
