x86/paravirt: Remove const mark from x86_hyper_xen_hvm variable
.. as "nopv" support needs it to be changeable at boot up stage. Checkpatch reports warning, so move variable declarations from hypervisor.c to hypervisor.h Signed-off-by: Zhenzhong Duan <zhenzhong.duan@oracle.com> Reviewed-by: Juergen Gross <jgross@suse.com> Cc: Boris Ostrovsky <boris.ostrovsky@oracle.com> Cc: Juergen Gross <jgross@suse.com> Cc: Stefano Stabellini <sstabellini@kernel.org> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: Ingo Molnar <mingo@redhat.com> Cc: Borislav Petkov <bp@alien8.de> Signed-off-by: Juergen Gross <jgross@suse.com>
