skylake: Do not pass VBT to FSP if display init not required
The FSP 2.0 change broke the logic for determining whether or not
to execute the GOP binary. Modify the FSP 2.0 code to do the right
thing and check for display_init_required() before passing VBT into
FSP and the GOP binary.
BUG=chrome-os-partner:61726
TEST=disable developer mode and ensure FSP does not run GOP
