Add the hooks to current code needed for Xen PVH. They will be filled
with code later when the related functionality is being added.
loader/i386/linux.c needs to include machine/kernel.h now as it needs
to get GRUB_KERNEL_USE_RSDP_ADDR from there. This in turn requires to
add an empty kernel.h header for some i386 platforms (efi, coreboot,
ieee1275, xen) and for x86_64 efi.

grub_xen_ptr2mfn() returns the machine frame number for a given pointer
value. For Xen-PVH guests this is just the PFN. Add the PVH specific
variant.

Rearrange grub-core/kern/xen/init.c to prepare adding PVH mode support
to it. This includes putting some code under #ifdef GRUB_MACHINE_XEN
as it will not be used when running as PVH.

Initialize the grant tab in a dedicated function. This will enable
using it for PVH guests, too.
Call the new function from grub_machine_init() as this will later
be common between Xen PV and Xen PVH mode.
