xen_vcpu_info is a percpu area than needs to be mapped by Xen.
Currently, it could cross a page boundary resulting in Xen being unable
to map it:
[ 0.567318] kernel BUG at arch/arm64/xen/../../arm/xen/enlighten.c:164!
[ 0.574002] Internal error: Oops - BUG: 00000000f2000800 [#1] PREEMPT SMP
Fix the issue by using __alloc_percpu and requesting alignment for the
memory allocation.
