[Intel-gfx] [PATCH 06/12] drm/i915: Constify the drm_i915_private pointer a bit more

[Damien Lespiau]

A lot of the WM functions are only reading from that structure and are
already using const. While converting the code to use dev_priv instead
of dev, I noticed a few places where we can give that hint.
