drm/i915: [sparse] __iomem fixes for debugfs
These were mostly straight forward. No forced casting needed. Signed-off-by: Ben Widawsky <benjamin.widawsky@intel.com> [danvet: fix conflict with ringbuffer_data removal and drop the hunk about the status page - that needs more care to fix up.] Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
