[SRU] [linux-oem] [PATCH v2 01/16] drm/i914/bios: amend child device config parameters

[Kai-Heng Feng]

From: Jani Nikula <jani.nikula at intel.com>

BugLink: https://bugs.launchpad.net/bugs/1746411

Add both some new and some old fields to child device config
parameters. Prepare for switching to just one child device config. Use
naming from struct old_child_dev_config for common fields.

No functional changes.
