mb/lenovo/t440p: Enable PCI 00:01.1 bridge for dGPU
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.
