drm/i915: Increase atomic update vblank evasion time with lockdep
All our mmio writes take forever with lockdep due to the constant
lock acquire&dropping we do. Ville has some patches to only acquire
the mmio spinlocks once instead for every single mmio, but those
aren't ready yet.
As an interim solution just extend our budget slightly when lockdep is
enabled, to avoid the rare and sporadic noise in CI.
v2: I forgot to add the FIXME comment ...
