drm/i915/gen9+: Fix initial readout for Y tiled framebuffers
If BIOS configured a Y tiled FB we failed to set up the backing object
tiling accordingly, leading to a lack of GT fence installed and a
garbled console.
The problem was bisected to
commit 011f22eb545a ("drm/i915: Do NOT skip the first 4k of stolen memory for pre-allocated buffers v2")
but it just revealed a pre-existing issue.
Kudos to Ville who suspected a missing fence looking at the corruption
on the screen.
