cortex_m: Do additional initialization during reset
SAM4L requires additional steps to be taken right after SYSRESETREQ is
issued in order to function robustly:
- CMSIS-DAP DAP driver needs to explicitly check for sticky bit
errors since it is possible for adapter to perform successful
write opration, report no errors and then, under the hood, do
some other things that will result in sticky bit being set.
- Debugger needs to wait for security system to finish
intialization and assert CDBGPWRUPACK before proceeding
