arm: Add support for memory-mapped m5ops
Add support for a memory mapped m5op interface. When enabled, the TLB intercepts accesses in the 64KiB region designated by the ArmTLB.m5ops_base parameter. An access to this range maps to a specific m5op call. The upper 8 bits of the offset into the range denote the m5op function to call and the lower 8 bits denote the subfunction.
