aarch64: Correct target state for hardware step

When using hardware step for doing stepping, the existing DSCR records
the event as external debug request. This will generate a SIGINT event
to GDB and causes it to stop the stepping process.
For aarch64, read DESR to check if the event is a hardware step and set
state to DBG_REASON_SINGLESTEP.
With this patch, GDB can now do source level stepping.
