drm/vkms: Update testing with IGT IGT_DEVICE

2025-11-04T10:51:15+00:00

VKMS is no longer in the platform bus, instead, it is in the faux bus. In addition, when present, IGT picks hardware drivers instead of virtual drivers, like VKMS or vgem, if they are not forced. Update the documentation to use IGT_FORCE_DRIVER instead of IGT_DEVICE.
