mb/google/kahlee/OemCustomize.c: Enable eDP HIGH_VDIFF

The careena board needs different video settings to pass eye diagram test,
which does not affect negatively the grunt board. In preparation for new
VBIOS, AGESA environment needs eDP high vdiff enabled.

BUG=b:111673328
TEST=Add debug code to AGESA to display set eDP. Build AGESA. Build and
boot grunt. Add new code to grunt, build and boot, verify eDP changed.
