For the VTL2 hyperv guest, currently the hv_vtl_init_platform() clears x86_platform.realmode_reserve/init while the hv_vtl_early_init() sets the real_mode_header.
Set the real_mode_header together with x86_platform.realmode_reserve/init in hv_vtl_init_platform(). This is ok because x86_platform.realmode_init() is invoked from an early initcall while hv_vtl_init_platform() is called during early boot.
