x86/sysfb_efi: Add quirks for some devices with swapped width and height commit d02f1aa39189e0619c3525d5cd03254e61bf606a upstream. Some Lenovo 2-in-1s with a detachable keyboard have a portrait screen but advertise a landscape resolution and pitch, resulting in a messed up display if the kernel tries to show anything on the efifb (because of the wrong pitch). Fix this by adding a new DMI match table for devices which need to have their width and height swapped. At first it was tried to use the existing table for overriding some of the efifb parameters, but some of the affected devices have variants with different LCD resolutions which will not work with hardcoded override values.
