i915: use io-mapping interfaces instead of a variety of mapping kludges
Impact: optimize/clean-up the IO mapping implementation of the i915 DRM driver
Switch the i915 device aperture mapping to the io-mapping interface, taking
advantage of the cleaner API to extend it across all of the mapping uses,
including both pwrite and relocation updates.
This dramatically improves performance on 64-bit kernels which were using
the same slow path as 32-bit non-HIGHMEM kernels prior to this patch.
