This is really platform initialization, for HVMlite it's invoked as
x86_init.oem.arch_setup(). Things like xen_setup_features(),
xen_init_apic() etc.
I suppose I can move it to xen_hvm_guest_init() but then we will have
some amount of code duplication. There is also a chunk of code there (in
xen_init_kernel()) that will probably be used for HVMlite dom0.

There is nothing PVH-specific, I said "(H)" mostly because that code is
the same is PV.
