Allow the arch backends to perform VM specific initialisation.
This will be later used to handle IPA size configuration and per-VM

This is a bit of a nit, but VM is a bit of an overloaded term in this context. Given what we do in the following patch (moving the global stage-2 init to be on a per VM -- virtual machine), I'd like to rename this to something less ambiguous.

How about kvm_arm_config_stage2? Or something along those lines?

No need to respin the series on this account, we can address it in a separate patch. But I think it would help understanding what is done where.

Thanks,

	M.
