[Intel-gfx] [PATCH 5/9] drm/i915: Covert HSW+ to choose DPLLS before disabling CRTCs

[Ander Conselvan de Oliveira]

Use the infrastructure added in a previous patch to choose shared DPLLs
and calculate clocks before touching the hardware.

v2: Don't set mode_set hooks since dev_priv is kzalloc()'d (Ville)
