From: Sonika Jindal <sonika.jindal at 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 eDP 1.4
where the values are different.
v2: Keeping old and new defines (Danvet), adding description in the commit
message
