[Intel-gfx] [PATCH] drm/i915: Correcting the reg definitions for PORT_DFT

From: Minu <minu.mathai at intel.com>

Display CRCs were not readable because the register defintions
for PORT_DFT_I9XX and PORT_DFT2_G4X were wrong.
MMIO offset needs to be added to these register offsets to fix them.

Issue: GMINL-6869
