Enable the dGPU on the Lenovo T440P. It uses the same code (roughly) of the T430S. By default, it is set to be disabled however it can be enabled via the nvram option enable_dual_graphics. Removed hybrid graphics options too as they are not valid for the T440p. Tested on a T440P with Ubuntu 18.04.4 with Kernel 5.3.0-29 (successful). Tested on same machine with Windows 10 1909 (machine check exception bluescreen).
