This extends the previous sanitychecking of device memory to read/write all the memory on the device during the device probe, ala memtest86, as an optional module parameter: i915.memtest=1. This is not expected to be fast, but a reasonably thorough verfification that the device memory is accessible and doesn't return bit errors. v2: Rebased.
