drm/i915/dg1: Reserve first 1MB of local memory
On DG1 A0/B0 steppings the first 1MB of local memory must be reserved.
One reason for this is that the 0xA0000-0xB0000 range is not accessible
by the display, probably since this region is redirected to another
memory location for legacy VGA compatibility.
BSpec: 50586
Testcase: igt/kms_big_fb/linear-64bpp-rotate-0
v2:
- Reserve the memory on B0 as well.
v3: replace DRM_DEBUG/DRM_ERROR with drm_dbg/drm_err
v4: fix the insanity
