drm/i915: add dev_to_i915 helper
commit 888d0d421663313739a8bf93459c6ba61fd4b121 upstream.
This will be needed by later patches, so factor it out.
No functional change.
v2:
- s/dev_to_i915_priv/dev_to_i915/ (Jani)
- don't use the helper in i915_pm_suspend (Chris)
- simplify the helper (Chris)
v3:
- remove redundant upcasting in the helper (Daniel)
