drm/print: require struct drm_device for drm_err() and friends

The expectation is that the struct drm_device based logging helpers get
passed an actual struct drm_device pointer rather than some random
struct pointer where you can dereference the ->dev member.

Add a static inline helper to convert struct drm_device to struct
device, with the main benefit being the type checking of the macro
argument.

As a side effect, this also reduces macro argument double references.
