drm/i915: Always use INTEL_INFO() to access the device_info structure
If we make sure that all the dev_priv->info usages are wrapped by
INTEL_INFO(), we can easily modify the ->info field to be structure and
not a pointer while keeping the const protection in the INTEL_INFO()
macro.
v2: Rebased onto latest drm-nightly
