[Intel-gfx] [PATCH] drm/i915: Consolidate cdclk hooks.

[Rodrigo Vivi]

We don't need 2 different blocks.
Specially with on in ordered older-to-newer and the other
one newer-to-older.

Let's start always using newer-to-older order
when it makes sense.

v2: Accept all good suggestions from Ville:
    - Remove \n since it is under 80 cols now
    - Use get/set/calc order on all blocks
    - Fix platform sorting
