drm/simpledrm: Do not upcast in release helpers
[ Upstream commit d231cde7c84359fb18fb268cf6cff03b5bce48ff ]
The res pointer passed to simpledrm_device_release_clocks() and
simpledrm_device_release_regulators() points to an instance of
struct simpledrm_device. No need to upcast from struct drm_device.
The upcast is harmless, as DRM device is the first field in struct
simpledrm_device.
