lspci for GP107M [GeForce GTX 1050 Ti Mobile]

Lot of thanks to Pierre Moreau for his suggestions of options in the kernel
command line :

-  Adding just 'nouveau.runpm=0' prevents the whole machine to freeze, but
'nouveau' FAILS to manage an external display with resolution 3840 x 2160 at
60Hz through DisplayPort.

-  Adding just 'acpi_rev_override=5' does NOT prevent the whole machine to
freeze.

-  Adding just 'acpi_osi=! acpi_osi="Windows 2009"' permits 'lspci' to succeed,
and 'nouveau' to successfully manage an external display with resolution 3840 x
2160 at 60Hz through DisplayPort.
