drm/i915: Replace open coded MI_BATCH_GTT
The (2<<6) virtual memory space selector harks back to gen3 and is mandatory given our use of GTT space for batchbuffers. On gen4+, use of the GTT became mandatory and bit6 marked reserved. However the code must now explicitly set (1<<7), which conveniently is also (2<<6). To clarify the meaning for future readers, replace the open coded (2<<6) with MI_BATCH_GTT.
