drm/i915: Implement Dbuf overlap detection feature starting from LNL
From LNL onwards there is a new hardware feature, which
allows to detect if the driver wrongly allocated DBuf
entries and they happen to overlap. If enabled this will
cause a specific interrupt to occur.
We now handle it in the driver, by writing correspondent
error message to kernel log.
v2: Initialize dbuf overlap flag in runtime_defaults (Jani Nikula)
v3: Unmask the overlap detection interrupt (Uma)
v4: use display over i915 (Jani Nikula)
v5: Use display instead of dev_priv (Jani Nikula)
v6: rebased to resolve merge conflicts
Bspec: 69450, 69464
