[0/9] drm/i915/bios: stop using vbt.ddi_port_info directly

Message

My long term plan is to reference all post-setup VBT child device
details through the encoder. We can add an (opaque) encoder->child
pointer, and forgo the dance to get to the relevant VBT details. This
will be helpful in, for example, adding support for multiple local
panels; the data must be made encoder specific instead of just using
i915->vbt.edp or i915->vbt.dsi directly.

The i915->vbt.ddi_port_info[] array stands in the way. Start hiding it
in intel_bios.c. We do gain a lot of intel_bios_*() accessors which may
seem noisy. But it seems to me this is a helpful iterative step no
matter what.

BR,
Jani.
