drm/i915/ltphy: Update the ltpll config table value for eDP

Browse Source 
When we get the eDP tables we reuse dp tables for some data rates.
We need to modify the 3rd config value of this table to 1 instead
of 0 since that is the only difference in the dp and edp table for
that particular data rate.
