Since commit 45c0673aac97 ("drm/i915/bios: start using the
intel_bios_encoder_data directly") we lookup the devdata for each port
in intel_ddi_init() and just return if the port is not present in VBT
(or if we didn't create a fake devdata for it if VBT is not available).

So in intel_display.c we don't have to check
intel_bios_is_port_present(), just rely on the check in

v2: Rebase 45c0673aac97 re-using that check in intel_ddi_init() instead
of adding a new one.
