[PATCH 5/7] drm/radeon: Renaming DP training vswing pre emph defines

sonika.jindal

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

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:

@@

# define DP_TRAIN_VOLTAGE_SWING_1200 (3 << 0)
+ # define DP_TRAIN_VOLTAGE_SWING_LEVEL_3 (0 << 0)
