to the correct Haswell values. Tested on t440p with dGPU on Ubuntu
18.04.4 with 5.3.0-28 kernel. Without patches dmesg reports Nouveau is
unable to read the VBIOS of the dGPU as it has an invalid checksum (I
checked that the ROM in CBFS is correct). With this patch DRM works
correctly with both the Nouveau driver and the Nvidia proprietary
driver. Windows 10 1909 also tested but generates bluescreen once GPU

- Sometimes it takes 20s of "pretending it's powered off" to run
