[ Upstream commit a6e23bec8ed184ed2a11080b28cdbd7a3024f0c0 ]

Add helper rdev_to_drm(rdev), similar to amdgpu, most function should
access the "drm_device" with "rdev_to_drm(rdev)" instead, where amdgpu has
"adev_to_drm(adev)". It also makes changing from "*drm_device" to "drm_device"
in "radeon_devicce" later on easier.
