Subject: [PATCH RFC 1/6] [HACK!] arm64/xen: create links to arch/arm include files and Xen code

Most of Xen support for ARM is common between ARMv7 and ARMv8.
Create links to the code under arch/arm (bleah).

Other, probably better alternatives:

- move the code to a different location, maybe the header files to
include/xen/arm and the code to drivers/xen/arm (still pretty ugly)?

- create a copy of the code to arch/arm64 (even worse);

Please advice on how you would like me to move forward on this.
