21d8017ace xen: Add basic hooks for PVH in current code
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.

fa57ea8463 xen: Modify grub_xen_ptr2mfn() for Xen PVH
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.

f06b0fd021 xen: Rearrange xen/init.c to prepare it for Xen PVH mode
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.

b85619206a xen: Carve out grant tab initialization into dedicated function
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.

72c9a50773 Remove xen VFB.
Due to XEN bug it prevents Linux boot. Remove it at least, until
	workaround is found.
