[PATCH RFC v1 01/52] drm/crtc: Start renaming struct drm_crtc::dev to drm_dev

[Uwe Kleine-König]

"dev" is usually used for struct device pointers. Using it for struct
drm_device pointers is irritating (for me at least). Introduce a
"drm_dev" as an alias with the intention to remove "dev" once all
drivers are adapted.
