Initialize the needed Xen specific data. This is:
- the Xen start of day page containing the console and Xenstore ring
page PFN and event channel
- the grant table
- the shared info page
Write back the possibly modified memory map to the hypervisor in case
the guest is reading it from there again.
Set the RSDP address for the guest from the start_info page passed
as boot parameter.

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.
