2022-10-06mb/lenovo/t440p: Enable PCI 00:01.1 bridge for dGPUNico Huber
An optional dGPU can be connected to the second PEG bridge: -[0000:00]-+-00.0 Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor DRAM Controller +-01.0-[01]-- +-01.1-[02]----00.0 NVIDIA Corporation GK208M [GeForce GT 730M] It's possible that the 01.0 bridge is never populated, but we have to leave it on anyway so 01.1 can be enumerated.
