drm/i915: Use consistent mappings for OpRegion between ACPI and i915
The opregion is a shared memory region between ACPI and the graphics
driver. As the ACPI mapping has been changed to cachable in commit
6d5bbf00d251cc73223a71422d69e069dc2e0b8d, mapping the intel opregion
non-cachable now fails. As no bus-master hardware is involved in the
opregion, cachable map should do no harm.
Tested on a Fujitsu Lifebook P8010.
