[Intel-gfx] [RFC] drm: split build lists one per line and sort

[Jani Nikula <jani.nikula@intel.com>]

While it takes more vertical space, sorted build lists with one object
per line are arguably easier to manage, especially when there are
conflicting changes.

Split anything with more than one object file.
