Start using struct intel_bios_encoder_data directly. We'll start
sanitizing the child device data directly as well, instead of the cached
data in ddi_port_info[]. The one downside here is having to store a
non-const pointer back to intel_bios_encoder_data.
Eventually we'll be able to have a direct pointer from encoder to
intel_bios_encoder_data, removing the need to go through the
ddi_port_info[] array altogether. And we'll be able to remove the cached
data in ddi_port_info[].
