[aarch64-port-dev ] RFR(XS): Provide information when hitting a HaltNode for architectures other than x86

Hi Xin,

(NOT a reviewer) The original instruction used should be dcps1 instead of dpcs1 - there's a misspelling in AArch64 assembler. Could you add a trivial fix to change dpcs1/2/3 to dcps1/2/3?

BTW, how did you test to hit the HaltNode?
