[Intel-gfx] [PATCH] drm/i915: Remove hole and padding from intel_shared_dpll

[Lucas De Marchi]

Reorder fields so we save 8 bytes per instance: this removes a 4-bytes
hole after enum intel_dpll_id and a 4-bytes padding.

Is this something desirable? I happened to be looking at
intel_shared_dpll and noticed the hole. I haven't checked any other struct
yet, but there are probably more and more important ones. This one saves
only 8 * I915_NUM_PLLS.
