From: Ander Conselvan de Oliveira <ander.conselvan.de.olive...@intel.com>
Split intel_ddi_pre_enable() into encoder type specific versions that
don't depend on crtc_state. The necessary parameters are passed as
function arguments. This split will be necessary for implementing DP
upfront link training.
