xen: arm: handle 64-bit system register access traps

Enterprise / Virtualization / Xen - Ian Campbell [citrix.com] - 29 July 2013 10:54 UTC

Wire up the vtimer handling to it.

Use a simplified version of the 32-bit cp-register macros to have convenient decoding of HSR register values. (simplified because we don't need them for passing to the assembler on 64-bit)
