Now that both xe and i915 store struct drm_device in drvdata, we can
trivially support struct device and struct pci_dev in
to_intel_display().
We do need to check for NULL drvdata before converting it into struct
intel_device pointer, though. Do it in __drm_device_to_intel_display().
v2: Add NULL check in __drm_device_to_intel_display() (Gustavo)
