[Intel-gfx] [PATCH v4 16/30] drm/modes: Switch to named mode descriptors

[Maxime Ripard]

The current named mode parsing relies only the mode name, and doesn't allow
to specify any other parameter.

Let's convert that string list to an array of a custom structure that will
hold the name and some additional parameters in the future.
