[PATCH] xen/arm: acpi: Include header file for version number

[Leo Yan <leo.yan@xxxxxxxxxx>]

On Arm64 Linux kernel prints log for Xen version number:

  [    0.000000] Xen XEN_VERSION.XEN_SUBVERSION support found

Because the header file "xen/compile.h" is missed, XEN_VERSION and
XEN_SUBVERSION are not defined, thus compiler directly uses the
string "XEN_VERSION" and "XEN_SUBVERSION" in the compatible string.

This patch includes the header "xen/compile.h" which defines macros for
XEN_VERSION and XEN_SUBVERSION, thus Xen can pass the version number via
hypervisor node.
