The actual GMCH_CRTL lives in the host bridge aka. device 0,
but device 2 has a read-only mirror on i85x/i865+. Document
that fact.
Also remove the ancient tales about where the defines are used.
Those haven't been true in a long time.

drm/i915: Clean up PCI config space reg defines2026-01-23T03:20:28+00:00Ville Syrjäläville.syrjala@linux.intel.com2025-12-08T18:26:36+00:00urn:sha1:29ed5593ca202da679493c25f82bf89a59114092
The PCI config space register defines in i915_drm.h are
a bit of a mess; Whitespace is all over the place, register
masks and values are defined in inconsistent ways.
Clean it up a bit.
