[PATCH] pci/quirks: Add quirk to reset nvgpu at boot for the Lenovo ThinkPad P50

On a very specific subset of ThinkPad P50 SKUs, particularly ones that come with a Quadro M1000M chip instead of the M2000M variant, the BIOS seems to have a very nasty habit of not always resetting the secondary Nvidia GPU between full reboots if the laptop is configured in Hybrid Graphics mode. T
