phy: qcom: edp: Unify generic DP/eDP swing and pre-emphasis tables

The current eDP and DP swing/pre-emphasis tables do not match the HPG
requirements for the supported platforms, correct the table accordingly.

The generic tables which can be shared as follows:

DP mode：
	-sa8775p/sc7280/sc8280xp/x1e80100
	-glymur
	-sc8180x
eDP mode(low vdiff):
	-glymur/sa8775p/sc8280xp/x1e80100
	-sc7280
	-sc8180x

The proper tables for SC8180X and SC7280 will be added in a later patch,
since they need separate table.
