I was debugging a problem that got fixed by a096883dda2c ("drm/i915/dsb:
Remove PIN_MAPPABLE from the DSB object VMA"). While that specific
problem is already fixed, others may pop up in future. This series
is tested by temporarily reverting that commit and ensuring we have
only a error message in the log, with graceful degradation to
"pass-through writes" like on platforms that don't support DSB.
