[PATCH 1/9] drm/i915: Don't pass crtc_state to intel_dp_set_link_params()

[Manasi Navare <manasi.d.navare@intel.com>]

From: Ander Conselvan de Oliveira <ander.conselvan.de.oliveira@intel.com>

Decouple intel_dp_set_link_params() from struct intel_crtc_state. This
will be useful for implementing DP upfront link training.
