    drm/amdgpu: Fix rejecting Tahiti GPUs · 3993a799

    eb4fd29a ("drm/amdgpu: bind to any 0x1002 PCI diplay class device") added
    generic bindings to amdgpu so that that it binds to all display class devices
    with VID 0x1002 and then rejects those in amdgpu_pci_probe.
    
    Unfortunately it reuses a driver_data value of 0 to detect those new bindings,
    which is already used to denote CHIP_TAHITI ASICs.
    
    The driver_data value given to those new bindings was changed in
    dd0761fd24ea1 ("drm/amdgpu: set CHIP_IP_DISCOVERY as the asic type by default")
    to CHIP_IP_DISCOVERY (=36), but it seems that the check in amdgpu_pci_probe
    was forgotten to be changed. Therefore, it still rejects Tahiti GPUs.
