[Intel-gfx] [PATCH v3 03/21] drm/i915: move modeset_update_power_wells earlier

[Imre Deak]

These functions will be needed by the valleyview specific power well
update functionality added in an upcoming patch, so move them earlier.

No functional change.

v2:
- no change
v3:
- rebase on latest -nightly
