xen: use the same hypercall mechanism for XEN and XENHVM
Currently XEN (PV) and XENHVM (PVHVM) ports use different ways to
issue hypercalls, unify this by filling the hypercall_page under HVM
also.

amd64/include/xen/hypercall.h:
- Unify Xen hypercall code by always using the PV way.
i386/i386/locore.s:
- Define hypercall_page on i386 XENHVM.
x86/xen/hvm.c:
- Fill hypercall_page on XENHVM kernels using the HVM method (only
when running as an HVM guest).
