Set look all ok,

I guess should start to think about how to write igt tests which would
target directly at dpt so this kind of issues wouldn't get missed.

Avoid the shrinker evicting the DPT during hibernate and
causing an oops. This might also fix DPT induced display faults
during high memory pressure (though still don't have a real
theory how that could actually happen).
Also add a i915.enable_dpt modparam to disable DPT usage via
the chicken bit. This can be useful when trying to debug suspected
DPT issues.

drm/i915/dpt: Treat the DPT BO as a framebuffer
drm/i915/dpt: Only do the POT stride remap when using DPT
drm/i915/dpt: Introduce HAS_DPT()
drm/i915: Add PLANE_CHICKEN registers
drm/i915/dpt: Add a modparam to disable DPT via the chicken bit
drm/i915: Move PLANE_BUG_CFG bit definitons to the correct place
