[PATCH 1/7] drm: Renaming DP training vswing pre emph defines

From: Sonika Jindal <sonika.jindal@intel.com>

Adding new defines, older one will be removed in the last patch in the series.
This is to rename the defines to have levels instead of values for vswing and
pre-emph levels as the values may differ in other scenarios like low vswing of
eDP1.4 where the values are different.

Done using following cocci patch for each define:
