arm64: tlbflush: Rename MAX_TLBI_OPS
Perhaps unsurprisingly, I-cache invalidations suffer from performance
issues similar to TLB invalidations on certain systems. TLB and I-cache
maintenance all result in DVM on the mesh, which is where the real
bottleneck lies.
Rename the heuristic to point the finger at DVM, such that it may be
reused for limiting I-cache invalidations.
