Matthias Welwarsky e17d1d4dc8 aarch64: add cache handling functions 
For now only D-Cache flush (Clean&Invalidate) and I-Cache
invalidate are implemented. That's enough for software breakpoints.

Matthias Welwarsky 4246fac240 aarch64: use correct instruction for software breakpoints 
External debuggers need to use HLT, not BRK. HLT generates a halting
debug event while BRK generates a debug exception for self-hosted
debugging.
