soc/intel/skylake: Remove dead `CONFIG_PRE_GRAPHICS_DELAY`

`CONFIG_PRE_GRAPHICS_DELAY` was only applied on a dead code path in
`igd.c` that is guarded by always selected `CONFIG_ADD_VBT_DATA_FILE`.
Nobody missed it for nearly a year, plus, it's not applied on the GOP
path, let's drop it.

On some systems, coreboot boots so fast that connected monitors
(mostly TVs) won't be able to wake up fast enough to talk to the
VBIOS. On those systems we need to wait for a bit before executing
the VBIOS.
