[Intel-gfx] [PATCH 1/6] drm/i915: export the stolen region as a resource

[Joonas Lahtinen]

+ Ville to comment if the removed code loses some meaningful comments
or not. I already went through the code doing consolidations, about a
year ago, so I may be blind to it.

You can take advantage of the newly establisted resource by using %pR
in the printk.

I sent a patch to convert the function signatures to resource_size_t
for a less painful future.

Maybe squash just the early quirks/header change portion of this patch
to that patch, then we can iterate on the i915 changes on a reminder of
the series on top of that.
