[PATCH 04/15] drm/i915: s/intel_mode_from_pipe_config/intel_mode_from_crtc_timings/

[Aaron Ma]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

BugLink: https://bugs.launchpad.net/bugs/1921318

Generalize intel_mode_from_pipe_config() to work on any two
arbitrary modes. Also relocate the code for the future, and
make it static since it's not needed elsewhere.
