On DGFX the register range has been extended to go up to 8MB. However we only actually use up to address 280000h, so let's increase it to 4MB. v2 (Lucas): add bspec reference and reword commit message to explain the 4 vs 8 MB used (requested by Matt Roper) Bspec: 53616 Cc: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Cc: Michael J.
