HVMlite guests (to be introduced in subsequent patches) share most

Where possible, HVMlite should share initialization with bare metal/HVM
and not PV(H).
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.
Sharing any code with the existing PVH code isn't useful, since PVH
support will be removed.
There is nothing PVH-specific, I said "(H)" mostly because that code is
the same is PV.
