The eDP PHY supports both eDP&DP modes, each requires a different table.
The current driver doesn't fully support every combo PHY mode and use
either the eDP or DP table when enable the platform. In addition, some
platforms mismatch between the mode and the table where DP mode uses
the eDP table or eDP mode use the DP table.
Clean up and correct the tables for currently supported platforms based on
the HPG specification.
Here lists the tables can be reused across current platforms.
DP mode：
-sa8775p/sc7280/sc8280xp/x1e80100
-glymur
eDP mode(low vdiff):
-glymur/sa8775p/sc8280xp/x1e80100
-sc7280

I went through everything and all the sequences are OK.
SC8180X will need changes, but it's already incorrect so this
doesn't necessarily affect it
Thanks!
