drm/i915: adjust framebuffer base address on gen4+
The tileoffset register only supports a limited offset in x/y of 4096,
so for giant screen configuration with a shared fb we wrap around.
Fix this by computing a linear offset in tiles (pages) and only use
the tileoffset register to offset within the tile.
